At Ortea Next, we have always paid attention to each step in the production process. Currently, we are finalising the production of the second batch of isolating transformers, which will contribute to the security of an important Data Center located in Indonesia, belonging to an online sales giant.
In particular, these are special isolating transformers, produced with high-quality and high-performance copper winding and grain-oriented sheet metal core. They are also equipped with intermediate sockets, an automatic circuit breaker, a measurement control unit with a communication module for remote monitoring, and they are supplied with an IP31 protection rating cabinet.
The customization of our solutions and close collaboration with the customer allow us to pair the product’s high quality with specific requirements; in fact, the design of these transformers is tied to that of the UPS, to which they must be coupled.
Thanks to its technical innovation and decades-long experience, Ortea Next is able to design and manufacture transformers that are suitable for any type of UPS system. In addition, partnerships with the world's leading manufacturers provide evidence of the high degree of reliability achieved.
Since 1969, the year Ortea Next was founded, low-voltage transformers have been at the heart of its business. The design and production knowledge and experience gained over the years allow us to offer high-quality, optimized and reliable products.
In addition to this, one of Ortea Next’s hallmarks has always been its extreme flexibility, which means it can ensure the quick development of dedicated solutions based on the Customer's technical specifications.
All this is achieved through customised design and our guarantee to maintain the same high levels of quality for standard products.
All design, production and marketing activities are carried out at Ortea Next's headquarters, thus ensuring continuous control and synergy among staff involved.
Ortea Next has manufactured and provided isolating transformers, including high power ones, installed in every continent, in contexts such as data centres, oil & gas, national security sites, and infrastructure.
Power prices continue to rise! Scheduling upgrades immediately is increasingly strategic.
The energy saving device POWERSINES by Ortea Next, ideal for retail sales points, public and private offices, service companies, etc., ensures an immediate reduction in consumption.

After purchasing the Powersines assets, Ortea Next completed the technical validation process and re-engineering of the technology purchased according to the quality standards that define it. The equipment has passed all its tests with flying colours and large-scale production has been launched.
Powersines ComEC by Ortea Next is a universal energy controller for commercial applications that enables power bill savings of up to 12% (the savings vary according to the system load types).
Powersines ComEC is installed downstream of the system’s main circuit breaker.
It dynamically controls and stabilises the voltage delivered at all loads, generating an immediate energy saving.
It improves the quality of the power and reduces maintenance costs.
ComEC does not require any change to the power system and, thanks to its small size, it can be easily connected to power switchboards. The sizing is immediate and depends exclusively on the power value of the main circuit breaker.
After the forced break due to the pandemic, Ortea Next's "full immersion" technical training sessions are starting again.
Following the "glocal" strategy, which aims at a "global" action but with a "local" application, Ortea Next continues to invest in the training of technicians from the distribution channel and customers, in order to intervene effectively and promptly on the installed machinery.
The training sessions will be delivered in English, Spanish and French (dates yet to be defined) according to the following schedule:
Enrollments for the English session are now open!
Registering is easy, just fill in the form at this link.
The training session is offered free of charge with a maximum of 12 participants and will be held at Ortea Next's headquarters in Italy. The candidates will be selected by Ortea Next at its sole discretion.
Ortea Next will provide lunch in our canteen and transfers to and from the airport and hotel. Participants will be responsible for the travel costs to Italy and accommodation at a hotel (Euro 78.00 per day including breakfast) located near the venue.
During the training session all the necessary notions will be acquired for:
The agenda is divided into theoretical and practical sessions:
At the end of the training session an official certificate will be issued, valid for three years, which is necessary to carry out any service activity on behalf of Ortea.
Service is considered one of our priorities: Ortea Next is pleased to announce that, starting from April 2022, the role of Business Unit Manager Service has been entrusted to engineer Matteo Sozzi.
This valuable acquisition will bring added value to Ortea Next, thanks to Matteo's experience in Power Quality and Energy Efficiency and his consolidated skills in "business development" and "IOT servitization".
"The next industrial revolution is in the 'Internet of things' which, through the acquisition of data on board the machine and the related processing algorithms, helps to implement the Service more and more in a predictive function. The adoption of these solutions will guarantee the customer optimum performance and, above all, continuity of service," says Matteo Sozzi.
The SIRIUS ADVANCE range of voltage stabilisers significantly increases a system’s power quality since it combines the voltage stabilisation function with power factor correction.
Moreover, SIRIUS ADVANCE, top of the range of the Ortea Next series of voltage stabilisers, has a multilingual, 10-inch touch display user interface, and is supplied already equipped with the “total protection kit” that comprises:
Input automatic circuit breaker.
By-pass switch with interlocked automatic circuit breaker.
Output motorised interlocked automatic circuit breaker.
The 200kVA ±30% SIRIUS ADVANCE pictured here is currently on its way to an important bank located in the Democratic Republic of Congo to resolve the customer’s power quality problems.
Our top-of-the-range model SIRIUS ADVANCE is available as standard from 60kVA up to 4000kVA and with different input voltage ranges: ±15%, ±20%, ±25%, ±30% adjustment.
Control and stabilisation, performed on the true RMS value, is carried out by a two-way DSP-microprocessor under the supervision of a second "bodyguard" microprocessor, operating with a software which has been developed specifically for ORTEA.
The columnar variable autotransformer with rollers (ORTEA design - without sliding contacts, which are subject to heavy wear & tear) is solid and very reliable.
The user interface is a multilingual 10” touch panel equipped with RS485 port. The display shows all the electric parameters (voltage, current, active power etc.), the information regarding the operating modes (power on; voltage regulation limits; increase/decrease of voltage regulation etc.) and the alarms (minimum and maximum voltage, maximum current, overtemperature, etc.).
A panel with the reactive power regulator RPC8BGA is installed to manage the power factor correction part. Designed to provide the desired power factor, while minimizing the wear and tear of capacitor banks, the SIRIUS ADVANCE are accurate and reliable in measuring and control and easy to install.
In line with the glocal vision that distinguishes us: “think globally and act locally”, we strongly believe in the added value that continuously training our employees, our distribution channel, and our customers’ technicians brings to end users of our products and solutions.
For a number of years, in fact, we have organised specific training courses at our headquarters on maintenance and repair operations for our equipment with a calendar of 2-4 annual sessions lasting one week.
The advent of the pandemic put a halt to this activity. The good news we’d like to share is that the decrease in restrictions imposed by governments on the movement of people allowed us to carry out the first training session for a group of maintenance technicians for an important African airport where our voltage stabilisers are installed.
With an eye on the pandemic situation, we’re already working on restarting the usual training activity as soon as possible.
The calendar for our sessions is usually divided into theory and practice:
As soon as possible, we will publish a calendar of sessions with an enrolment form.
Final testing phase for this Enersolve machine, tailored to the needs of the customer, a large glass-works located in northern Italy.
75% of the Customer's production derives from the use of recycled glass. To achieve this important result, also from the circular economy and environmental sustainability point of view, it uses a large furnace that works by means of electrodes that cause the fusion of glass through the formation of an electric arc. In addition to being an energy-intensive technology (overall process consumption approx. 7gWh/year), service continuity is very critical and requires a quality power supply that meets well-defined parameters.
This is why the customer chose an Enersolve solution that, in addition to guaranteeing an expected energy saving of between 3% and 4% in this specific case, ensures compliance with the parameters necessary for the proper functioning of the system.
In particular, a 3200kVA Enersolve ESL-10 complete with numerous optionals:
The equipment measurements are truly impressive: 7000x1000x2300h mm weighing almost 6000 kg.
The ENERSOLVE range is available in three models:
The added value of the ENERSOLVE solutions is undoubtedly represented by the ENERCLOUD platform, which is essential for displaying and analysing energy parameters and a prerequisite for obtaining the benefits linked to Industry 4.0 plans. The on-board instruments make it possible to read and record the values of all the plant's electrical parameters, hence processing energy-saving data in real time. The method used to process the energy-saving data is based on the principles of the ESPRO protocol approved by ENEA (National Agency for New Technologies, Energy and Economic Development) after 3 years of joint studies.
The ESPRO protocol enables dynamic savings measurement: it is not based on measurements before and after the implementation of the energy efficiency implementation but rather enables continuous savings measurement.
We’re pleased to have participated in Middle East Energy this year too; as usual, it allowed us to meet partners and customers of a historically important region for us.
In particular, we’d like to thank all our staff (Ahmed - Sales director, Petio - Area sales manager, Paolo and Nicola - Business Unit Manager), who, in addition to meeting numerous customers and prospects at our stand, let us relive the experience through photos that we’re pleased to share with you.
The reliability of Ortea voltage stabilisers is proverbial, can it be increased even more?
Sure! Thanks to the Ortea Cloud monitoring system, you can check all the operating parameters of your stabiliser in real time, wherever you are. In addition to the generation of alarms, this allows timely and predictive intervention, in order to minimise possible disruptions, that would cause additional costs due to unproductive personnel, loss of raw materials, machinery damage and malfunction, etc.
The multi-user mode allows you to create multiple user profiles on one device, giving access to the platform to one or more plant managers. Ortea offers a direct monitoring service on request, interfacing with the relevant technical team. Although considered by many companies, innovative monitoring solutions are rarely implemented: Ortea Cloud is currently being offered at a promotional price, now is the ideal time to discover it and start taking advantage of all the benefits it has to offer.
We are pleased to announce that ORTEA has been invited to speak at the Hackathon Days, organized as part of the Reestart Project promoted by ICU and ENEA.
The web conference will take place on February 22nd and 23rd 2022 and will focus on innovative solutions on renewable energy technologies, energy efficiency measures and circular economy.
Don't miss Petio Dimitrov's speech at 2.20pm this afternoon, focused on ORTEA’s customized solutions designed and conceived to help Companies improve their power quality and energy efficiency parameters.
Middle East Energy will take place in Dubai from 7th to 9th March: the leading global trade fair for the energy sector, in which Ortea has been a satisfied exhibitor for many years is back!
After a long period of only being able to do this virtually, we look forward to meeting you in person at our booth H3-C11.
To arrange a meeting, please send an e-mail to ahmed.lazzem@ortea.com or petio.dimitrov@ortea.com.
Formerly known as Middle East Electricity, the new Middle East Energy, taking place at the Dubai World Trade Centre, is one of the world's leading energy trade fairs, bringing together the main players in this market: from large energy suppliers to multi-utility decision makers to innovative start-ups.
The event aims to be an industry platform focused on technological innovation and the promotion of energy transition culture.
Today's industrial systems are evaluated in terms of maximising production continuity, a characteristic that is achieved above all by exploiting process automation to the full. As a result, we are witnessing an increasing introduction of electronic and IT equipment in production lines, devices that are very sensitive to Power Quality.
In order to ensure the high production performance required, industrial systems must be supplied with power of excellent quality, both in terms of continuity as well as intrinsic characteristics. In fact, the main causes of unscheduled system downtime, malfunctions, and serious damage to electrical equipment and infrastructure are due to poor power quality.
According to statistical studies, approx. 80% of disturbances due to poor power quality are generated internally at the end-user (downstream) system. Typically, these disturbances are due to non-linear loads (inverters, welding/punching machines, drives, robots, electronic equipment in general) that generate harmonics on the grid, or to the presence of high-power loads (large motors, for example) that can generate disturbances.
The remaining 20% of disturbances come from the Grid (upstream), i.e. the power supplier. Even the most advanced transmission and distribution systems cannot guarantee supply with absolute continuity and perfect quality. In this sense, the recent complexity of the generation world (think of the increasing diffusion of renewables such as solar and wind power) has certainly had and will increasingly have a significant impact on the quality of the power supplied.
Measuring the Power Quality of one’s electrical system is almost never a simple matter. First of all, it is necessary to identify whether any problems are coming from "upstream" or "downstream," and then try to understand where, when, and how they manifest themselves…
In order to collect information and electrical data to be analysed, it is necessary to carry out one or more measurements, or better said, veritable measurement campaigns. To carry out such campaigns, extensive skills are required; it is unlikely that any one person can cover all areas in a given system. It becomes necessary to involve several people: an expert in electrical measurements (often also a system expert), a solution expert (a Power Quality specialist), and the operational personnel in the company, since there is no one better able to provide the right information (even if usually the effect is known but not the cause that generated it).
The measurement campaign is a key point in solving PQ problems. It is the first step in the investigation process and, if it is done in the wrong direction, it will lead to failure.
It is important at this stage to have a comprehensive and in-depth discussion with those who are familiar with the process and the problems encountered, and to determine what is happening, in which system situations, at what times/on which days/in which seasons, and whether the problems started before or after any system changes. If the problems involve a certain piece of equipment, it would also be a good idea to talk to the manufacturer to understand the reason of certain incorrect behaviour.
This phase also includes documentation checks, going over the wiring diagram with verification that it is updated to the current state, since this document is fundamental to be able to identify distorting and sensitive users in order to understand which are the users affected by any malfunctions. Looking at the bills for an entire calendar year is also important, especially for systems that are not in continuous operation. In addition, if there is a supervisory IT system with data logging, it should definitely be consulted, verifying that the measuring instruments used provide truthful data.
Before taking the measurements, it is advisable to carry out an inspection to examine the system. Important information can be gathered from a "sensory" point of view, by sight (state of the machinery, presence of evidence of short circuits, overloads, overheating, presence of pollution of possibly conductive dust, etc), by ear (humming in the cabinet, and their trend as a function of active loads), and by "feel" (cabinet temperature, humidity).
At this point, the picture should be clear and it will be necessary to think about:
The choice is fundamental and strategic, since the measurements must provide the useful data on which to reflect to solve the problem. Measuring should not be overdone, risking complicating the problem with a volume of data to be analysed and managed that can become unnecessarily embarrassing.
Where: establish in which points of the system the measurements are to be performed: at the terminals of the disturbed loads, at the terminals of the disturbing loads, just downstream of the MV/LV transformer, etc. In systems with complex topology, the choice of where to take the measurement is fundamental; making a mistake in the measurement point means having to "throw away" all the measurements previously taken and starting again from scratch.
When: at full load (or during start-up of the main loads) if the maximum current and voltage harmonic distortion and/or the minimum voltage is to be measured. With minimum load (e.g. evening hours) if possible voltage variations beyond the nominal value are to be evaluated. In the case of problems encountered during certain processes or system states, measurements should be conducted reproducing these conditions.
For how long: measurements aimed at identifying max THDI and max THDV can take less than an hour, if carried out when the system is at maximum load. On the other hand, measurements aimed at voltage or power profiling should be conducted for at least one full week (CEI EN 50160). Statistically based investigations (e.g., voltage gap counts and their duration and depth characteristics) need a continuous measurement of at least a few months.
Which measurements to take and with which instruments: this depends on numerous factors; it is not possible to generalise. It is a case-by-case assessment; the value added lies in the skill of the electrical measurement experts.
Ortea is able to carry out Power Quality measurement services in both industrial and tertiary power systems, aimed at the identification of voltage/current distortion problems or slow/rapid voltage variations, with subsequent identification and technical/commercial proposal of power factor correction, filtering and stabilisation solutions.
A modernly organised company that wants to keep up with the times and the needs of an increasingly competitive global market must stay aligned and updated with new technologies.
Ortea SpA is constantly looking for advanced technologies and methodologies to develop the best Power Quality solutions, keeping design, development and production costs under control, in order to offer the market the usual quality but at competitive prices.
That is why our design engineers have been using 3D design software for over a decade.
Once the machine has been designed from an electrical performance standpoint, it then becomes necessary to translate calculations and electrical schematics into a hardware application. With the aid of 3D software, it is possible to design equipment down to the smallest details, with enormous advantages that have repercussions on the entire production chain. All this becomes even more significant taking into account that one of the flagships of Ortea SpA is the ability to modify the designs of its standard equipment, adapting them to the specific customer needs, and to produce high power machines with many components.
At this point, to allow workers to assemble the equipment, the designer prints a series of views of the design which, however, are never comprehensive. For this reason, several terminals have been placed in production at Ortea that can be consulted by assembly workers. This solution allows workers, in case of doubts, to view the machine in all its parts and from all angles, with the advantage of avoiding assembly errors and wasting time for both designers and assemblers.
Thanks to the synergy among all departments, Ortea SpA is constantly evolving to provide quality solutions that ensure the peace of mind of its customers.
2021 was a year characterized by extraordinarily high energy prices (as you can see from the data published by Iea - International Energy Agency) and numerous studies show that this trend will be confirmed for 2022.
The root causes are the same: skyrocketing commodity prices and the costs of CO2 emissions paid by energy companies and energy-intensive industries, a vicious circle which at the moment shows no signs of trend reversal, despite Governments’ effort to control prices.
At this juncture, it becomes increasingly important and strategic to quickly plan investments to reduce the consumption and the running costs of your electrical system.
Our Power Quality solutions, especially our Icar branded Power Factor Correction Systems and our Enersolve branded Energy Efficiency Smart Devices, guarantee immediate savings.
Ortea is your partner to guide you through the right choice (www.next.ortea.com).
Ortea SpA has adopted a certified corporate Quality System, which, inter alia, envisages that all equipment produced is subjected to extensive testing.
In certain cases, especially for large solutions, the customer requests to carry out the tests with the presence of a technician. This procedure is universally known as FAT (Factory Acceptance Test).
Ortea SpA exports its solutions all over the world, and in this pandemic period when travel can be a problem, it has become necessary to find a solution to perform such testing. Thanks to modern technology, FATs can be performed online, using video cameras and simple teleconferencing software.
In this case, the machine to be tested was a voltage stabiliser for an end customer located in a sub-Saharan African country. We cannot help but dedicate a few lines to this extra-large solution: a Sirius 2000kVA digital voltage stabiliser with ±35% output regulation, complete with total protection kit, weighing 11100kg and measuring 7000x1600x2000mm, made in two separable splits to facilitate shipment and placement in the destination premises.
Thanks to the videoconference connection and to the portable video camera, the customer was able to follow all the tests foreseen (lasting approx. 5 hours) step by step and, at the end, sign its acceptance directly by sharing the documentation produced.
Enlit Europe, the new brand that combines European Utility Week & Powergen Europe, is a trade fair that aims to be a guide to the energy transition. This evolution is shaped by established players, external innovators, innovative start-ups and also end users. Enlit Europe aims to bring all of these communities together in order to seize current opportunities, highlight those of the future and inspire the next generation.
Ortea SpA could not be missing and, after the three days of participation in Enlit 2021, it is now time to take stock.
The companies that participated, undoubtedly of excellent standing, were for the most part related to the Ortea context from various points of view, including:
Our sales team reports excellent ideas for possible applications of our Power Quality solutions in new market segments and numerous contacts with both potential customers and potential suppliers of innovative technologies.
Despite a participation "on tiptoes", the assessment of these three days of the trade fair is therefore positive.
A separate chapter concerns the positive feelings reported by the entire Ortea Spa Sales Team which, after almost two years of the pandemic, only participation in a trade fair "in person" can arouse.
The Ortea staff wishes everyone to enjoy every day of this adventure called "life".
May the new year be special, amazing and happy!
We can define the culture of a company as the set of values that characterise the identity of a firm. When we talk about values, we refer to the company mission and vision, to the management of the team, and to all those aspects that define the approach of the company, both within and outside of the organisation.
By referring to these concepts, we can say that:
The corporate culture is important both for employees and for the company heads. In the first case, the workers are more likely to enjoy their time in the workplace when they adapt to the corporate culture. At the same time, the corporate culture is also important for employers, so that the workers who adapt to this won’t just be happier, but also more productive. When an employee is in harmony with the corporate culture, it’s likely that they will wish to work for the company for longer. This entails a big advantage in terms of productivity and retention on the part of business owners, who can count on a motivated team that wishes to bring value to the organisation.
With this in mind, Ortea has launched the Work Groups Project. To summarise, this is a project in which work groups are formed, which are not homogeneous, within the corporate organisation with the task of proposing projects for improvements focused on two macro-areas:
The project is divided into three phases:
• Phase 1: Implementation and definition of the roles of the work groups’ members, collection/processing and presentation of the proposals.
Currently, we have completed Phase 1. Shortly, the winning project will be voted on; each group will assign their preference to one of the works of the other groups and the project that obtains the most preferences will pass to Phase 2. We’ll see what happens!
A special thanks to the Paolo Cazzaniga Employment Consultancy Studio for its priceless and effective collaboration in implementing and coordinating this project, in particular to Paola Cazzaniga and Luca Riboldi.
October is also in line with the excellent quarter just closed for Ortea SpA. The main KPIs, such as turnover, orders, net financial position, and EBITDA are all positive and improving compared to previous years.
We expect to close 2021 with the current positive trend and a 2022 with even more promising results, spurred by a global economic recovery and by a market, like the Power Quality one, which is always growing.
The company has coped with the pandemic without particular repercussions, demonstrating that it has a market, a professional production capacity of high standing, which can withstand extraordinary events of a historical significance.
Partnership projects on an international scale are under way to strengthen the technological and commercial offering, ensuring our customers a range of innovative and tailor-made solutions.
This gives us hope for a profitable future that will benefit stakeholders and the families of Ortea employees.
In conclusion, just to say:
Massimiliano Scarpellini - Ortea SpA CEO
The traditional 2022 Ortea desk calendar, which is being distributed to our partners, is dedicated to sustainable development and, as a result, environmental sustainability.
Ortea SpA is sensitive to this issue. Not only does it produce Power Quality solutions, which contribute to reducing energy consumption, and certify the company quality system, which also comprises the ISO 14001 standard (suitable management system for keeping the environmental impact of operations under control and systematically researches improvements thereto in a consistent, effective, and, above all, sustainable way), but Ortea also has scheduled structural works in the pipeline. These works include adopting an energy co-production system with the use of solar panels and “full-electric” vehicles for the company fleet.
And we can’t forget the continuous commitment of our team of engineers dedicated to developing new technologies that may effectively contribute to energy efficiency and, therefore, to the reduction of CO2 emissions in the atmosphere.
The calendar is intended to be a small tool to contribute to reflection, having the 17 Sustainable Development Goals defined by the UN in the 2030 Agenda as its central theme.
1. End poverty in all its forms\ Today, there are still many people living on less than 1.25 dollars a day; it’s unjust in terms of the dignity of any human being and could come to an end with cooperation between countries and the implementation of social systems and measures to protect everyone.
2. End hunger, achieve food security and improved nutrition and promote sustainable agriculture\ Every one of us has the right to enough food throughout the year. This is a basic concept, but one that is still neglected. In any case, it could be sustained, for example, with sustainable food cultivation and production systems and by preserving the ecosystem and diversity of seeds and plants to cultivate.
3. Ensure healthy lives and promote well-being for all at all ages\ An essential goal is reducing the global rate of maternal mortality and preventing the death of new-borns and children below 5 years old due to preventable causes. How? For example, by ensuring healthcare for everyone and supporting the research and development of vaccines and medicines for diseases, whether contagious or not.
4. Ensure inclusive and equitable quality education and promote lifelong learning opportunities for all\ Education can truly guarantee all young people a better future. One step forward would be to ensure that everyone, men and women, can read and write, eliminating all forms of gender discrimination and promoting equal access to all levels of education accompanied by high-quality teaching.
5. Achieve gender equality and empower all women and girls\ Still today, women and girls are the target of discrimination. Rooting up any form of violence against women in the private and public spheres, such as their sexual exploitation, is essential.
6. Ensure availability and sustainable management of water and sanitation for all\ Water is the source of life and it is essential that this is accessible to everyone: a statement urging us to ensure universal access to clean, drinkable water by 2030 and suitably hygienic conditions, with special attention to more vulnerable people.
7. Ensure access to affordable, reliable, sustainable and modern energy for all\ Today, energy systems are fundamental to everyone’s daily life. As a result, an important step is that of making them accessible to everyone.
8. Promote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all\ Work gives us the possibility to live our lives in dignity. Supporting economic growth and attaining high levels of productivity can help our survival.
9. Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation\ Both infrastructure and industry are important for supporting all economic development and our well-being; they become sustainable and trustworthy with technological development and research.
10. Reduce inequality within and among countries\ Every country should have equal opportunities and rights at an economic and global level: because of this, it is essential that growth in domestic revenue is achieved and sustained. To move in this direction, it is urgent that, by 2030, tax, salary, and protection policies are promoted that gradually ensure greater equality among the population.
11. Make cities and human settlements inclusive, safe, resilient and sustainable\ The environment that surrounds us can dramatically influence our habits and lifestyles. Because of this, an improvement in terms of the sustainability of our living spaces by 2030 is a goal that cannot be neglected.
12. Ensure sustainable consumption and production patterns\ Our planet needs to be respected and protected. In this regard, by 2030, it is important to reduce waste and chemical substances released, especially by large, multi-national companies, using sustainable policies that are characterised by product recycling.
13. Take urgent action to combat climate change and its impacts\ Climate change is the order of the day and stands out in everyone’s eyes. It’s a situation that can no longer be ignored and must be confronted by 2030, with global, sustainable policies and strategies so as to curb environmental risks and current natural disasters.
14. Conserve and sustainably use the oceans, seas and marine resources for sustainable development\ The conservation and sustainable use of our oceans, seas, and all those resources within them are important to our lives. Reducing marine pollution, along with a sustainable management of the ecosystem and protection of the underwater environment, are essential goals for protecting our health.
15. Protect, restore, and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss\ Preserving our planet is a task that is entrusted to every one of us and, for this reason, it is essential that, by 2030, we pursue combined action for protecting, restabilising, and promoting the sustainable use of the earth’s ecosystem.
16. Promote peaceful and inclusive societies for sustainable development, provide access to justice for all and build effective, accountable and inclusive institutions at all levels\ A better future for each of us is possible, but only if there is a drastic reduction in violence and mortality. It’s a vision that seems a long way away today; however, it is feasible with the implementation of peaceful societies, access to justice for everyone, and the existence of responsible institutions by 2030.
17. Strengthen the means of implementation and revitalize the global partnership for sustainable development\ The implementation of the Agenda requires the heavy involvement of all members of society: from companies to the public sector, from civil society to philanthropic institutions, from universities and research centres to media and culture organisations.
All countries are called upon to contribute to the effort to guide the world onto a sustainable path, without distinguishing between developed, emerging, and developing countries any longer. This means that each country must commit to defining its own sustainable development strategy that enables the 2030 Agenda goals to be attained, accounting for the results obtained as part of a process coordinated by the UN.
Years of experience in applied development, acquired both in the field of voltage stabilisers and power factor correction, has allowed Ortea technicians to offer (as optional for Orion Plus and Sirius, standard for Sirius Advance) power factor correction banks integrated into the voltage stabiliser enclosure.
Thanks to its expertise in designing and producing both types of equipment, this solution is entirely designed and made by Ortea, with an optimised size for ensuring maximum performance.
From 80kVA to 320kVA, the power factor correction bank is produced using single-phase capacitors made of high-density metallized polypropylene; starting from 400kVA, we use capacitors of the same type, but three-phase, ensuring greater strength.
The advantage is the result of having a load that is fed in a stabilised way and that has a high power factor and, as a result, the maximum active power available. In addition, for the 1000kVA (and above) power stabilisers, the product involves installing a blocking reactance that protects the capacitors from any harmonic distortions generated by non-linear loads, increasing the plant’s power quality even further.
In practice, this product makes it possible to exploit all the power factor correction and voltage stabilisation advantages, without having to manage two separate purchase orders and without having to coordinate the double installation, perhaps at two different times, with a consequent saving in cost.
Enlit Europe is the new brand in which the European Utility Week and POWERGEN Europe will merge.

The European edition will feature several online meetings and a three-day event in Milan from November 30th to December 2nd, 2021, where participants will meet and inspire each other and develop discussions and actions to make progress in the energy transition.
We look forward to seeing you on our stand 8.F54 to show you our Power Quality and Energy Efficiency solutions.
Two of the four Oxygen sag compensators, intended for an important, international European airport, are in the testing phase. The cabinets, on the customer’s explicit request, have taken on a particular, yellow uniform, and the colour hasn’t gone unnoticed.
As a result of an order at the end of 2019, for which three Oxygens were provided, the customer, happy with the results achieved and engaged in a project for expanding the gates, ordered four more of them.
The supply involves two 500kVA Oxygens and two 320kVA Oxygens, both with ±10% input voltage regulation and coverage for voltage sags of up to -40%, with indoor IP54 protection.
The Oxygens will power and protect the electronics of the underground conveyor belts that sort and carry baggage directly to the gates. These new belts have been devised and designed to speed up the handling of baggage and, therefore, the service offered to travellers. Being activated by sophisticated electronic equipment that is very sensitive to power quality, sophisticated protection devices needed to be installed on them. Oxygen was chosen from among various options on the market.
The more modern the equipment, and the more electronics are required, the more serious are problems caused by voltage sags. With the growing number of renewable energy generation plants, voltage sags, fluctuations, and frequency deviations are on the rise.
Oxygen, thanks to the suitable size of power components and a remarkable response time (<3 milliseconds), is able to resolve voltage sags of a maximum duration of one minute. The energy required is taken directly from the mains.
Current models are able to cover voltage sags of up to 50% of the nominal value (-50%).
The voltage compensation on the buck/boost transformer’s primary winding is performed by IGT static circuit breakers controlled by a micro-controller. The micro-controller system controls the output voltage and determines the opening or closure of the IGBTs, ensuring the best regulation.
The use of double-conversion technology ensures insulation from mains disturbances and distortions and, together with the use of electrolytic capacitors, makes it possible to create machines for high loads.
The range of Oxygen sag compensators:
Compared to the standard model, the K model is equipped with an input automatic circuit breaker, an output automatic circuit breaker, and a manual by-pass line with interlocked automatic circuit breaker.

The growing use of power electronic devices is causing an increasing level of harmonic distortion in the electrical systems, which is why energy suppliers require the use of harmonic blocking reactors.
Blocking reactors, together with capacitor banks, create power factor correction and harmonic current filtering banks.
This type of reactor is usually constructed with a magnetic core that can guarantee high linearity values even with large increases in current compared to the nominal value.
A detuning power factor correction system prevents any amplification of harmonic currents and voltages caused by resonance between the capacitor and inductance capacitance of the electrical system.
By adding a correctly sized reactor to the power capacitor, a low resonant circuit is formed (usually below the fifth current harmonic) which prevents higher order harmonics from flowing into the capacitors and damaging them.
ORTEA’s blocking reactors are assembled with aluminium or copper coils.

Destined for a prestigious project for a grand Hotel in Qatar, two truly special Sirius voltage stabilisers are in the process of being shipped.
Manufactured “off-catalogue”, according to the customer’s specifications, the two voltage stabilisers are top-of-the-range Sirius models and have a power of 1600kVA and extreme input voltage regulation: ±40%.
These specifications led to the production of very large magnetic components; in fact, the total weight of the machines is a good 11,700 kg.
The Sirius range of the highest-performance and most complete voltage stabilisers in our production, is encountering a lot of success on the market.
Sirius is available for powers ranging from 60 to 6000kVA, with ±10%, ±15%, ±20%, ±25%, ±30%, +15/-35%, and +15/-45% adjustment. The control logic is managed by two DSP microprocessors (one that implements the control and the other that manages the measurements) that stabilise the output voltage, adjusting the true-RMS (root mean square) thereof. The whole system is supervised by a third (bodyguard) microprocessor that checks the correct operation of the other microprocessors.
In addition to the generous size and additional protections, which make the equipment very reliable and durable, the user interface is undoubtedly another very important feature.
Consisting of a 10-inch, multilingual touch display (equipped with an RS485 port), it can provide information on the state of the lines upstream and downstream of the voltage stabiliser (voltage, current, power factor, active power, apparent power, reactive power, etc.), the operating state of the stabiliser (it displays all the information relating to each operating mode: on/off, adjustment limit reached, increase/decrease in adjustment, etc.), and any alarms (minimum and maximum voltage, maximum current, excessive temperature, etc.).
If connected to a network via Ethernet with an RJ45 cable, the display can, in addition, be remotely transmitted to a PC using VNC software. It is, in addition, possible to interface with the stabiliser using the Modbus TCP/IP protocol (a standard protocol in communicating between industrial electronic devices). The system is also equipped with two USB ports that can be used to download the data stored and upload software updates from the control card.
The interface possibilities widen with Ortea Cloud, the new Ortea platform for remotely monitoring voltage stabilisers.
Ortea SpA, which has been active for years in the low-voltage power factor correction sector with its own ICAR by OrteaNext brand, in pursuing its strategy to complete its Power Quality offering, introduces its new line of medium-voltage power factor correction products. The range includes both components for compensating reactive power and studying and designing fixed, automatic systems.

Quality and reliability: two words that have always been key to Ortea SpA’s vision. The R&D department engineers are constantly looking for new solutions and means for improving our products.
As far as electro-mechanical stabilisers go, the various modes for achieving this purpose include increasing the monitoring of the components, going into ever more detail, and choosing a predictive way that generates alarms so as to warn of any failures or disruptions.
Despite rigorous tests performed in the company, extended use, in the absence of suitable maintenance, can sometimes generate issues owing to component wear. Through monitoring and predictive analysis, however, it is possible to avoid any stabiliser disruptions and machine stoppages, with the resulting added costs owing to unproductive personnel, wasted raw materials, damage to/malfunctions of the connected machines, etc.
To this end, the Ortea SpA engineers have developed OMR (Ortea Monitored Rollers), an electronic system capable of monitoring the operation of all the components of the regulator columns: the beating heart, together with the electronics that govern the operation thereof, of the stabiliser.
Currently available as optional for the top range: Sirius and Sirius Advance, OMR is able to:
The analysis of these data, displayed on the machine’s touch display, and the generation of alarms in the event of critical conditions make it possible to analyse the stabiliser’s behaviour and anticipate any disruptions with timely interventions.
OMR, an additional device for increasing the already well known reliability of Ortea targeted stabilisers and for improving the consequent peace-of-mind of the customer who installs our products.
The manufacturing sector for bicycles and related components is an important one in Italy; it boasts a long tradition and very high level of quality, and has survived global competition. It is a jewel in the crown of Italian manufacturing.
Our customer, always attentive to the environment, is a producer of components for competition bikes, and already had a 1000kVA Enersolve solution operating in the company, which was installed in 2017. Being happy with its results, both in terms of making the electrical system more efficient and in terms of improving Power Quality, the customer decided to install a new 630kVA machine on a new production line.
The ENERSOLVE range is available in three models:
The added value of the ENERSOLVE solutions is undoubtedly represented by the ENERCLOUD platform, which is essential for displaying and analysing energy parameters and a prerequisite for obtaining the benefits linked to Industry 4.0 plans. The on-board instruments make it possible to read and record the values of all the plant's electrical parameters, hence processing energy-saving data in real time. The method used to process the energy-saving data is based on the principles of the ESPRO protocol approved by ENEA (National Agency for New Technologies, Energy and Economic Development) after 3 years of joint studies.
The ESPRO protocol enables dynamic savings measurement: it is not based on measurements before and after the implementation of the energy efficiency implementation but rather enables continuous savings measurement.
In the general context of Power Quality issues, power outages are among the most annoying events.
The CEI EN 50160 Standard defines the supply interruption as “a condition in which the voltage at the supply terminals is lower than 5% of the reference voltage”.
A power outage can be categorized as:
Scheduled interruptions are typically due to the execution of programmed maintenance works on the power grid. The effects of a scheduled outage can be minimized by the users by taking timely measures.
Accidental interruptions, on the other hand, are unpredictable and largely random events, generally caused by the intervention of operating or protective devices.
Under normal operating conditions, the annual number of outages can vary from a few dozen to several hundred, depending on the characteristics of the network. According to the statistics, 70% of outages last less than a second; accidental long outages usually originate from external causes or events that cannot be predicted by the supplier: this is the reason why it is impossible to state typical values of annual frequency and duration. Nevertheless, the ARERA statistics (Italian Regulatory Authority for Energy, Networks and Environment) are very indicative in this sense: by improving the quality of the network infrastructure, the number of interruptions is dramatically reduced. Under normal conditions, the annual frequency of such interruptions can vary from less than ten to about fifty, depending on the areas.
The effects of interruptions, even temporary, mainly affect the most sensitive users:
Power outages typically cause the equipment to stop, in particular the categories listed above, but they can also cause some damage. In particular, the aspect that we want to take into consideration in this article is the voltage recovery transient that takes place immediately after the interruption.
Among the many different network events that can lead to a power outage, we can identify two macrocategories:
This is the dynamic In the first case (picture 1). The mains voltage drops during the overload due to the voltage drops caused by the current on the line impedances: as a consequence the electromechanical voltage regulation devices (both those located upstream of the delivery point and those possibly present downstream) tend to counteract this lowering by going to the “maximum rise” operating state. However, if the overload persists and a protection is released, it is likely that when the voltage is restored, the regulating elements are still in the condition they were in just before the release. Consequently, if the voltage returns to its nominal value when it is restored, the users can be stressed by a voltage significantly higher than the nominal one.
In the second case (picture 2), the tripping of the protections can be followed by subsequent attempts by the automatic recovery devices of the energy distribution company. In this case the multiple transients due to the different O-CO-CO cycles of the circuit-breakers multiply the stress in a very short time.
In addition, after an interruption the voltage transient may have an initial overshoot. In general, the stress on the most sensitive equipment can cause damage (for example to electronic boards), which in the case of sophisticated industrial users have a great impact in terms of costs for production stops (identification of the fault, replacement of the component, provided that it is available and not to be ordered from the distributor or the manufacturer).
To reduce the stress caused by these events, ORTEA engineers have studied a solution, which is supplied as a standard on ORION PLUS, SIRIUS and SIRIUS ADVANCE, as well as on the largerst ENERSOLVE Energy Efficiency Smart Devices: it is the system of return to the optimal voltage through supercapacitors.
Picture 1: tripping of networt overload protections.
__
Picture 2: tripping of a short circuit or earth fault protection and subsequent O-CO-CO maneuvers.
This feature, also called “voltage shock absorber” or “soft-start” (words that make its effect more understandable), intervenes in the event of a power failure.
The special supercapacitors mounted on the electronic board store the energy, which is necessary to drive the motors of the voltage regulator rollers to the position of “minimum” regulation.
Upon restoration of the power supply, the mechanical inertia of the voltage regulators will absorb the transient, thus delivering to the downstream users a voltage with a “tame” transient, much less dangerous than that coming from the network. In fact, the voltage is gradually restored to the load, as it is apparent in pictures 1 and 2.
In the majority of industrial plants the power factor correction system is centralized, with high capacity capacitor banks usually equipped with harmonic blocking reactors to protect capacitors from harmonics in the current.
When choosing a capacitor bank, it is necessary to pay attention not only to the quality of the capacitors inside the cabinet, but also to the quality of the other components and to the different solutions adopted by the manufacturer, in order to choose a device which will be efficient, long-lasting and easy to maintain.
Internal structure\ ORTEA SpA manufactures all ICAR APFC with removable rack. It is preferable to choose a capacitor bank with removable racks: it’s the best way to reduce time and problems during maintenance.
Regulator\ It is the intelligent element, which controls the capacitor bank, so it is very important. The regulators on board the ICAR APFC are all microprocessor-based, with several measuring and alarm functions: they will help you understand how the APFC works and how the electrical system to be rephased behaves. You will appreciate it a lot during the capacitor bank’s life and in particular when there will be problematic situations.
Contactors\ In order to guarantee excellent long life and reliability, ORTEA SpA ORTEA SpA uses only good well-executed contactors. For standard PFC systems, contactors have to be with damping resistors to limit capacitors inrush current (AC6-b). For detuned PFC systems are enough standard contactors (the function of the peak smoothing It is performed by the blocking reactance).
Load break switch\ It is the operation element, the one which has to bear the current of the capacitor bank also in case of overload. According to IEC 60831-1 regulation it has to be dimensioned with a nominal current which is at least 1.43 times the nominal current of the capacitor bank.
Steps\ ORTEA SpA manufactures ICAR APFC with a step-by-step that can ensure good accuracy in the correction of the power factor. Typically ICAR realizes its APFC with linear steps, which allows the optimization of the number of electrical combinations obtainable. Harmonic blocking reactors In detuned APFC, intended for plants with distorted currents and/or resonance risks, the reactors are intended to defend capacitors from harmonic currents, which would damage them. ORTEA SpA designs and builds most of the reactors used in its ICAR APFC, based on the considerable experience gained.
Ventilation\ The ICAR APFC are all made with forced ventilation. This reduces the thermal stress of the on-board capacitors, whether electrically (harmonic overload) and/or ambient (high temperature in the cabin).
Filters for the ventilation system\ They protect the capacitor bank from the entrance of dust and foreign bodies, which could worsen its thermal situation. During the commissioning, especially if with cable arrival from below, it must be carefully placed so that inbound there are no alternative routes for cooling air: this occurs through the opening of cables passage, if it is not sealed appropriately with ad hoc shaped sets or foams.
Ortea Cloud, Ortea SpA's platform for remote monitoring of the Orion Plus and Sirius range of stabilisers, is being promoted at a special price until the end of 2021.

The italian Minister for Ecological Transition, Dr. Cingolani, stated that "the electricity bill increased by 20% during the last quarter, we are expecting a further 40% increase for the next quarter."
The cause can be summarized in the increase of raw material prices and CO2 emission costs paid by energy companies and energy-intensive companies. This is happening not only in Italy, the scenario is the same all over the world.
Our Power Quality solutions, in particular Power Factor Correction Systems and Energy Efficiency Smart Devices guarantee immediate savings.
Ortea is at your disposal to guide you in the right choice.
The client is a large plastic moulding company located in north-eastern Italy.
The green trend led them to select a monitored energy-saving solution. Not only that, but large fluctuations in the mains supply cause operational problems for the presses… Enersolve is able to solve this problem by guaranteeing a controlled voltage output in case of mains variations in the range of ±10%.
The purchase by the client was made through an ESCO company in EPC (Energy Performance Contract) mode, specialised in this type of intervention. This method will allow the client to reduce the costs of their investment to zero thanks to the monthly savings produced by the ENERSOLVE solution. The savings have been estimated to be about 200,000 kWh per year.
The machine, a 2500-kVA ENERSOLVE ESL-10E (model complete with three electronic, emergency and exclusion by-passes), intercepts the total power of the system, under a Mt/Bt transformer, via a 4000A busbar.
This is an XXL equipment, 5400x1000x2100 mm in size with a weight of approximately 4,900 kg.
The ENERSOLVE range is available in three models:
The added value of the ENERSOLVE solutions is undoubtedly represented by the ENERCLOUD platform, which is essential for displaying and analysing energy parameters and a prerequisite for obtaining the benefits linked to Industry 4.0 plans.

The remote monitoring of equipment functions and parameters is a requirement of an increasingly IOT-oriented market.
This is how Ortea Cloud, Ortea's new platform for remote voltage stabiliser monitoring, was born. It replaces and surpasses "Stabimon", the first monitoring software designed and developed more than ten years ago by Ortea. In addition to the Sirius range, Ortea Cloud is also available for the Orion Plus range.
The system consists of the Edge component, an ARM Linux gateway installed on board the machine, and the Cloud platform.
The Edge component communicates with the unit via industrial protocols, constantly acquiring operating parameters and generating telemetry via an intelligence that can vary the sampling rate according to the status of the machine. The collected information is immediately saved on the gateway, which is able to store it locally for a period of two months in case of loss of connectivity with the cloud. When connectivity is re-established, the information is immediately sent all together.
The on-board gateway application can generate alarms:
The data received from the cloud platform is processed by a rules engine capable of generating Real Time alarms based on dynamic rules, sending email notifications and storing telemetry and alarms in the database.
The cloud platform is able to show the telemetry of the measurements collected by each machine as a time series. In this way, the user can analyse their behaviour by comparing even different measurements on the same graph, thus highlighting any anomalies.
The platform manages the entire lifecycle of the machine and gateway, from installation to replacement in the event of failure. Data is stored on databases specifically designed for logging time series, allowing rapid retrieval for dashboard display or export to spreadsheets.
Ortea Cloud therefore makes it possible to:
The platform is available both to the end customer and, with different access credentials, to any person in charge of running the plant. Ortea offers a direct monitoring service on demand, by interacting with the relevant technical team.
Once logged in with the parameters provided by Ortea, an intuitive and easy-to-use dashboard appears, with the stabiliser or stabilisers, if more than one, active in the cloud.
Ortea Cloud is offered in two versions: the basic version (Ethernet) or the basic version + modem (should it not be possible to connect the stabiliser to a network). Access to the platform is free for the first year and there are no additional costs for software licences and updates. Thereafter, an annual or three-year renewal fee is required.
Milan, Italy - September 1st 2021
ORTEA, leading global provider of power quality solutions, is pleased to announce the completion of the acquisition of the "Assets" from POWERSINES Ltd, including Brand, Patents and the complete product range.
With this acquisition Ortea will complete its commercial offer, including low power voltage optimizers and at the same time revitalizing the Powersines sales network, previously active in the European markets.
Ortea is therefore continuing its business growth despite the effects of the pandemic, the global supply chain crunch and the vicissitudes of the holding Company.
"I am extremely satisfied with the economic and financial results achieved so far in 2021, all of which are positive and a clear improvement on previous years. Double-digit percentage improvements, thanks to the formidable professional contribution and relentless commitment of all our employees and our technical and commercial partners, who share the philosophy of close synergistic cooperation aimed at mutual and constant improvement" (Massimiliano Scarpellini, CEO Ortea SpA).
Quality and reliability have always been etched in Ortea Spa's DNA; we like to think of the customer's peace of mind when they choose our equipment.
That's why the R&D department is always looking for ways to improve our products.
One way to achieve this is to ensure that components are monitored and that alarms are generated to allow a timely and predictive intervention, in order to minimise possible disruptions that may cause additional costs due to unproductive personnel, lost raw materials, damage/malfunctioning of machinery, etc.
On this matter, important innovations are about to be implemented on the ORION PLUS and SIRIUS ranges.
Stay tuned to find out.

In addition to this, one of ORTEA SpA’s hallmarks has always been its extreme flexibility, which means it can ensure the quick development of dedicated solutions based on the Customer's technical specifications.
All this is achieved through customised design and our guarantee to maintain the same high levels of quality for standard products.
All design, production and marketing activities are carried out at ORTEA SpA's headquarters, thus ensuring continuous control and synergy among staff involved.
ORTEA SpA has manufactured and provided isolating transformers, including high power ones, installed in every continent, in contexts such as data centres, oil & gas, national security sites, and infrastructure.
Modern industry is becoming increasingly automated and the sensitivity of industrial processes to Power Quality issues is always on the rise. At the mains connection point, the energy taken, while within the regulatory requirements, may not be optimal for use. We purchase power without being able to negotiate the quality that we need. Price and quality of the power are often complementary; together they define the value attributed to electricity consumption.

The customer is a large Italian pasta company that has implemented a new project for two production lines located in North Africa. The plant is powered by four transformers split between the two lines. Each transformer has a parallel emergency line fed by generators to be used in the event of a power failure. For logistical reasons, the customer wanted a single piece of equipment for each line, which, in addition to stabilising the voltage for both transformers with the relevant circuit breakers, would also have the motorised drive part on board for switching from mains power to emergency-line power, using the ATS (Automatic Transfer Switch) system.
The solution designed by Ortea's engineers is an equipment assembled in a single cabinet consisting of two 1600 kVA Sirius stabilisers, with ±15% input regulation, including all the drives.
Ortea’s production then created the “Sirius two-in-one” to be installed on each of the two lines. To facilitate shipping, handling and installation they were shipped in multiple parts.
Ortea has always been able to design and build special equipment to meet customer's requirements, often helping them in the design phase and adapting its solutions to any plant and logistics situation.
The Sirius range is available for powers ranging from 60 to 6000kVA, with ±10%, ±15%, ±20%, ±25%, ±30%, +15/-35%, and +15/-45% adjustment. The control logic is managed by two DSP microprocessors (one that implements the control and the other that manages the measurements) that stabilise the output voltage, adjusting the true-RMS (root mean square) thereof. The whole system is supervised by a third (bodyguard) microprocessor that checks the correct operation of the other microprocessors
Ortea is pleased to announce that from June 2021 the Ortea Spa sales team will be joined by two new members, the engineers Davide Cuppari and Petio Dimitrov.
Davide Cuppari, who has an extensive experience in the world of critical power and business development skills, including international ones, is assigned the role of Italy Sales Manager.
“The Power Quality solutions and services offered by Ortea are very wide-ranging and the company's technical expertise is of great depth. In the near future, also thanks to the path taken by ARERA with the latest TIQE, there will be a lot of attention on the issue of energy quality: we are ready”, says Davide Cuppari.
Petio Dimitrov, who was born in Bulgaria and grew up in Morocco, graduated in Electronic Engineering in Milan and has many years of experience in B2B sales in the plant engineering sector with a focus on foreign countries due to his extensive language skills. Petio will join and enrich our international sales team.
“In order to achieve the targets set by the various states in terms of energy transition, the world needs to change rapidly. This will intensify the existing challenges for electrical networks across the world in terms of continuity of power supply, longevity of equipment and its safety. My professional goal is to be close to customers to overcome these challenges that are particularly dear to me; Ortea, with its organisation and expertise, has provided me with the ideal environment to accomplish this”, says Petio Dimitrov.
“I am confident that Davide and Petio’s experience and professional background will be of great help to our company. Our expectations are to ensure Ortea's continued growth, that would not be possible without an efficient customer service and a mutual relationship with our partners", states our CEO Massimilano Scarpellini.
The belief that product quality and Customer satisfaction are the core of a modern organization, led to the implementation of a certified Company Managing System.
A modern Company that wants to accept the challenge of today’s business scenario cannot do so without conforming to standardized organizational criteria.
Customer satisfaction, product quality and responsible occupational practices are the basis on which the Company’s activities can be consolidated. ORTEA SpA understood this a long time ago: the first ISO 9001 approval dates back to 1996.
Today ORTEA SpA Integrated Managing System is approved by Lloyd’s Register according to the main Standards:
This means that ORTEA SpA can ensure that its performance is optimized in terms of internal process management, commitment towards environmental issues and attention to health & safety at work within the frame of a single Managing System.
Odyssey, ORTEA's high-power static voltage stabilizers: ideal when a high regulation speed is a must, as in the case of data centers located in areas where poor voltage quality jeopardizes their smooth operation.
3 high-power static voltage stabilizers Odyssey with ±20% input voltage range are currently being put into operation (2 of 2000kVA and 1 of 2500kVA): they will improve the power quality of a large data center located in the Persian Gulf region.
In the Odyssey static stabilisers, the compensation of the input voltage fluctuation is managed by exploiting the double-conversion technology. The traditional regulating system is replaced by the converters that generate the necessary voltage once the control system has detected an incorrect situation.
The main feature of such configuration is the fast response (<3msecs), which guarantees real-time correction and voltage steadiness on the load side.
The double conversion technology also ensures insulation from disturbances and distortions in the grid. Thanks to suitable electrolytic capacitors, high power loads demands can be met.
Odyssey maintains the usual operational features: the regulation is performed on each phase independently, the load can vary between 0 and 100% on each phase and the operation is not affected by the load power factor. The unit can operate with or without the neutral wire.
Standard units cover a wide power range and offer a double input connection so that with the same unit two different input variations (±15/±20% or ±25/±30%) can be dealt with.
A 10” multilingual touchscreen on the front door works as user interface. By surfing the available menus, the electrical measures can be read and setting parameters adjusted. The interface is fitted with an Ethernet communication port, which, via dedicated «client», allows remote monitoring. Communication with the control system can be established also via RS485 serial bus and Modbus TCP/IP protocol.
The standard unit is housed in an IP2X metallic enclosure with RAL9005 finish for indoor installation.
Extracting fans ensure losses dissipation and unit cooling.
Electricity Authorities: The Electricity Authorities, force companies distributing electricity to apply financial penalties to utilities that have a substantial contractual power and low energy cos phi (generally 0,9). The correct power factor of the electric plant allows you to avoid those penalties, which often are not reflected in the bill, and then are paid by the final user without even realizing it.
Economic convenience: Economical benefits due to penalties elimination and current reduction, with consequent optimized dimensioning of the components and increased life expectancy.
Energy efficiency: The power factor correction reduces the "useless" inductive currents required by the loads and that impacts the entire electric network, both in the generation, transmission and distribution stages. Power factor correction is therefore an important contribution to the energy efficiency of both the user's electrical system and the electricity grid.
Power Quality: In many industrial electric plants supplied by MT there is a tension considerably distorted, due often to excessive load of MV/LV transformer. The correct Power Factor Correction with a consequent load reduction by the transformer allow to bring it back to the operating conditions within the linearity limits, substantially reducing the voltage distorsion. Furthermore the proper Power Factor reduces the presence of harmonic currents.
ENERcloud is the cloud platform for our ENERSOLVE “Intelligent energy efficiency devices”.
The tools on board enable the reading and recording of values for all the plant’s electric parameters, processing, in real time, the energy-saving data. The method used for processing the energy-saving data is based on ESPRO protocol principles approved by ENEA (Italy's National Agency for New Technologies, Energy and Sustainable Economic Development) after three years of joint research.
The ESPRO protocol enables savings to be measured dynamically. In fact, the protocol isn’t based on the measurement before and after implementing the energy efficiency measures; instead, it enables energy savings to be measured continuously.
In developing the ESPRO protocol, we started out from a quote of Galileo Galilei: "Measure what can be measured, and make measurable what cannot be measured.” In fact, it involved identifying a method that took account of the continuous variations in the two principal elements that contribute to the final result: the supply source and the combination of load mix moment by moment. Only continuous, not one-off, measurements of these quantities, which constantly and significantly vary, make it possible to determine, with certainty, the efficacy of the measures.
We began with the IPMVP (International Performance Measurement and Verification Protocol), the protocol for checking the results of energy efficiency, water efficiency and renewable energy projects in any field, from civil engineering to industrial sites. This method involves comparing energy consumption before and after the installation of an energy efficiency system. The limitation is that it adapts very well to systems in which the trend of the two parameters cited above is almost constant. However, in a real plant the situation is quite different, the trend in supply voltage, power, and load mix used is very different in each moment.
We added the analysis of the VDE-AR-E 2055-1 method: a standard that VDE created and that adapts IPMVP in the area of energy efficiency. It introduces the concept of variable energy saving depending on the type of load and the classification - in three categories - depending on their sensitivity to voltage variation. The limitation is in identifying the load mix installed in the plant, a piece of data that must be accurately known and must not, subsequently, vary.
The ESPRO protocol involves continuous measurement. The measurements are carried out every 15 minutes and, during a 30-second measuring window, the saving is frozen for 10 seconds, thus obtaining an actual difference between the instantaneous power and what the system would have used without the Enersolve installation. The measurement is repeated for the machine’s entire service life.
The total energy saved during the day is the sum of the individual measurements that repeat the method involved in the IPMVP protocol 96 times per day and exceed the VDE standard requirements, intercepting, sample by sample, the change in load mix.
The guarantee provided by Enersolve, thanks to this ESPRO functionality, refers to the total savings in kWh.
In practice, however, what is the effect when Enersolve is assembled in the plant?
The graphic below, downloaded from ENERcloud, shows the active power absorbed by an actual plant. The lower part shows the power value for the plant with the Enersolve system installed. The upper part, instead, shows the power that the plant would have used without the Enersolve system installed.
In this graphic, instead, the consumption of the system can be seen, day by day, with (green bar) or without (red bar) the Enersolve system.
ENERcloud, all the information in your hands…wherever you are.
The latest-generation electronics installed in the ENERSOLVE equipment makes it possible to measure, send, and store all the sensitive measurements, the energy saving, and the state of the machine in the cloud.
Thanks to the intuitive, Web-based software, it is possible to obtain all the necessary information in real time, in any part of the world and with any device.
ORTEA is happy to announce that, starting from June 1st 2021, the role of Sales Manager for Italy will be taken over by Eng. Davide Cuppari. Davide has excellent international business development skills and a lot of experience in the field of critical power.

In the near future, also thanks to the path taken by ARERA with the latest TIQE, there will be a lot of attention to the issue of power quality: we are ready", declared Davide Cuppari.
The new Power Factor Correction System catalogs are available online.
The 2021 range has been completely remodeled.
We invite you to profit of our spare parts promotion, special discount 25%, for the month of May only.
The quality and reliability of our products has always been a principal feature, a goal that our project engineers pursue every day with controls and tests performed continuously.
In this case, we wanted to check the reliability of some readings of the tools on board the Oxygen by comparison with class A tools, according to the CEI EN 61000-4-30 standard. One was mounted at the input stage and one at the output stage of an Oxygen 500-10-40 that was installed and operating perfectly in our production plant. There are two tools for comparison: LINETRAXX PEM735 of Bender; the clocks of each are synchronised with that of the Oxygen panel.
The purpose of the test is to check the correctness and precision of the voltage sag readings. Contrary to what you might think, voltage sags often occur on electric lines considered to be of good quality, such as Italian ones.
We have identified a single-phase voltage sag entering the second phase as can be seen from the screen-shot of the tool:
In this case, the second phase has a residual tension of 88.54%.
Here, we’d like to recall that the definition of a voltage sag is a change in voltage starting at -10% of the nominal voltage up to -95% (i.e. residual voltage of 5%) with a duration of 10ms to 1 minute.
We detect the event, accurately, in the operator’s panel mounted on board the Oxygen:
At this point, Oxygen intervenes to compensate for the sag; in fact, in the period of time in which the event occurred, the tool does not detect any voltage sag on output:
An additional confirmation of Oxygen’s performance.
Oxygen is available in two models:
Oxygen 10-40 (from 200 to 3200kVA) with input voltage compensation ±10% (continuous) and compensation for voltage sags of up to -40% of the nominal voltage per 1 minute.
Oxygen 15-50 (from 200 to 2000kVA) with input voltage compensation ±15% (continuous) and compensation for voltage sags of up to -50% of the nominal voltage per 1 minute.
The supply of 16 80kvar 400V MINImatic HP20 power factor correction devices, with IP55 carpentry, is complete: 1280kvar supplied in total.
The equipment was manufactured with robust capacitors made of high-gradient metallized polypropylene (nominal voltage: 460V) and is characterised by a particularly robust carpentry with a high degree of protection.
The equipment is destined for a large European port and was, therefore, manufactured with IP55-degree protection carpentry.
This big piece of infrastructure has significant installed power, which is often, however, distributed across very wide areas: reducing the currents in play is essential, both for the efficiency of the plant and for environmental sustainability.
In this sense, capillary power factor correction is always an excellent choice.
Ortea is pleased to announce the arrival of Enerlux as a new shareholder in the company structure.
"We are sure that Enerlux will create important commercial and industrial synergies with Ortea, by increasing the mutual value in the interest of the stakeholders" says our CEO, Massimiliano Scarpellini.
Enerlux is a historic international industrial player, with a strong know-how in the production of capacitors and power factor correction systems for both low and medium voltage (www.enerlux.eu).
"I strongly believe in this project” - says Monica Ronchini, CEO of Enerlux - “although at the moment we enter with a minority stake, our aim is to increase our presence in the share capital of Ortea”.
The Sirius range of the highest-performance and most complete voltage stabilisers in our production, is encountering a lot of success on the market. In recent months, in fact, we have manufactured and delivered a significant amount of equipment destined for customers spread across every part of the globe.
The Sirius range is available for powers ranging from 60 to 6000kVA, with ±10%, ±15%, ±20%, ±25%, ±30%, +15/-35%, and +15/-45% adjustment. The control logic is managed by two DSP microprocessors (one that implements the control and the other that manages the measurements) that stabilise the output voltage, adjusting the true-RMS (root mean square) thereof. The whole system is supervised by a third (bodyguard) microprocessor that checks the correct operation of the other microprocessors.
In addition to the generous size and additional protections, which make the equipment very reliable and durable, the user interface is undoubtedly another very important feature.
Consisting of a 10-inch, multilingual touch display (equipped with an RS485 port), it can provide information on the state of the lines upstream and downstream of the voltage stabiliser (voltage, current, power factor, active power, apparent power, reactive power, etc.), the operating state of the stabiliser (it displays all the information relating to each operating mode: on/off, adjustment limit reached, increase/decrease in adjustment, etc.), and any alarms (minimum and maximum voltage, maximum current, excessive temperature, etc.).
If connected to a network via Ethernet with an RJ45 cable, the display can, in addition, be remotely transmitted to a PC using VNC software. It is, in addition, possible to interface with the stabiliser using the Modbus TCP/IP protocol (a standard protocol in communicating between industrial electronic devices). The system is also equipped with two USB ports that can be used to download the data stored and upload software updates from the control card.
The new 2021 LV transformers catalogue, expanded and enriched with more technical details, is available online.

This Orion Plus, 630kVA voltage stabiliser with ±15% regulation, will improve the Power Quality on a ship’s propulsion power supply.
Its placement in particularly aggressive conditions has led to a series of design features.
The enclosure is equipped with C3 anti-corrosion paint (based on the ISO12944 standards) to counteract deterioration owing to salt and produced with protection rating IP23, i.e. it is protected from water sprayed with an angle of less than ±60°. The “seismic dampers” serve to absorb mechanical vibrations and stresses that derive from the ship’s movement.
The ORION PLUS model is a three-phase electro-mechanical stabiliser available in standards for different ranges of input voltage fluctuation (±10%, ±15%, ±20%, ±25%, ±30%, +15%/-35% and +15%/-45%), and for a wide range of powers (from 30kVA to 2000kVA).
Beyond the production standard, ORTEA SpA is able to develop and produce special equipment with great flexibility according to the user’s “specifications” thanks to the experience we’ve gained over numerous years of applied technological development.
ORTEA SpA, with its brands ORTEA, ICAR, and ENERSOLVE, offers a unique range of products and services for Energy Quality and Energy Efficiency of low-voltage electrical networks: voltage stabilisers, sag compensators, power factor correction systems, transformers, reactors, and active harmonic filters.
The first batch of a supply of reactors (55 units in total) to be installed inside fixed, 5 MVAR power factor correction systems, in order to block harmonic currents, is on its way.
Their function is to compensate the reactive power on 24 kV networks with an IGBT insertion system, thus a very fast - practically real-time - compensation system.
Although the application of these systems is horizontal for all those customers who use electricity with a medium-voltage connection, in this case the final customer is a producer of electronic parts for consumer electronic goods: computers, mobile phones, and peripherals.
Since 1969, the year in which ORTEA was founded, the magnetic parts (transformers and reactors) have been at the centre of its business and, thanks to vast experience and close collaboration with customers, the company has developed specific knowledge that allows them to produce reactors to respond to various problems that may derive from their great variety of uses.
In addition to this, one of ORTEA SpA’s hallmarks has always been its extreme flexibility, which enables the quick development of dedicated solutions based on the Customer's technical specifications.
In particular, we produce the following for both indoor and outdoor use:
All design, production and marketing activities are carried out at ORTEA SpA's headquarters, thus ensuring continuous control and synergy among personnel involved.
The 960Kvar MULTImatic FH20 system, designed for the power factor correction of an ORC (Organic Rankine Cycle) thermodynamic cycle turbogenerator, is ready for dispatch.
The Rankine cycle developed for this application is similar to that used by a traditional steam turbine except that the working fluid, in this case, is an organic fluid with a high molecular mass. This enables the effective production of electricity in a wide power range, beginning with a low-temperature heat source both from renewable sources (biomass, solar heating) and from residual heat sources from primary industrial thermal processes (exhaust fumes, fluid leaving gas turbines).
The system is a special version: single cable arrival from above with an automatic switch as requested by the customer for their plant connection requirements.
The FH20 range, with blocking inductors, is a solution that is used when a current with a high harmonic content (THD) and/or with high risk of resonance with the MT/bt transformer circulates in the electrical system.
In these cases, the installation of “normal” power factor correction equipment, without barrier inductors, can cause the rapid degeneration of the capacitors and instigate dangerous electrical and mechanical stresses in the system power components (cables, busbars, switches, transformers).
The barrier inductors protect the capacitors from the harmonic distortions and, at the same time, exclude the risk of resonances, but they leave the harmonic content of the plant current unaltered (if you wish to reduce the system harmonic content, you need to install active filters. Consult us).
ORTEA SpA offers two types of power factor correction solutions with barrier inductors: one with 180Hz blocking frequency (detuned to 3.6 times the line frequency) and a second with 135Hz (2.7 times).
It’s worth underlining that the lower the detuning frequency, the more robust the system, since the inductors must have a larger iron core.
With the aim of boosting investments, the Italian Government has just approved a package of incentives to increase the energy efficiency of companies. The Enersolve technology, thanks to the official certification issued by ICIM, falls within the scope of this legislation. Check if your Country is offering similar incentives and do not hesitate to contact us, if you want to know more!
ORTEA is finalizing the manufacturing of the first batch of isolation transformers for a large Data Center project for the Ministry of Interior of a North African Country.
The transformers are equipped with a measurement control unit with RS485 communication module and Modbus protocol for remote monitoring with BMS system. They will be coupled with the already installed UPS.
The supply includes a total of 30 isolation transformers, 4 of which of 1250kVA and 2 of 1600kVA.
A second batch will follow to complete the supply.
The installed control unit allows the customer to remotely monitor the operation of the transformer, including measurement and control functions.
These transformers are highly customized, as a matter of fact their design is linked to the design of the UPS to which they must be coupled. A close cooperation with the customer is therefore an essential requirement for the development of the most suitable solution.
Thanks to decades of experience, ORTEA is able to design and manufacture transformers for any kind of UPS. The partnership with major manufacturers worldwide provides evidence of the high degree of reliability achieved.
The voltage supplied by the electrical network to the user’s terminals should be perfectly sinusoidal, at a constant frequency and without interruptions. Actually, the mains voltage usually presents several anomalies, as shown by the measurements carried out on site, and as taught by the CEI EN 50160 standard, a guiding document in the world of power quality fundamentals.
Non-continuity is among the major problems afflicting the power supply: this can be caused by the tripping of circuit breakers, interruption of the conductors, maintenance or works on the grid, atmospheric events, etc. Voltage sags are another big issue: they can be considered as close relatives of voltage interruptions when they are short and deep; instead, they are more similar to voltage variations when they have limited depth and long duration. Another problem is the voltage fluctuation, which can be fast or slow, usually due to network maneuvers, difficulties of adjustment by the energy distributor, disconnection or starting of large loads, etc. The duration of a voltage fluctuation can be several hours.
A "classic" solution to slow voltage variations is the voltage stabiliser, which can be electromechanical or electronic. LV voltage stabilisers for large powers, let's say >100kVA, typically operate thanks to a “buck-boost” transformer connected in series to the line and suitably piloted by voltage regulators. They are available in a wide range of sizes: from the smallest ones capable of handling an apparent power of a few kVA, up to those managing several MVA. They guarantee an excellent output voltage accuracy, up to ±0.5% of the nominal value, provided the input voltage variation remains within the range shown on the data label. In the most recent versions, the voltage regulation is obtained through electronic actuators, whose performances allow a higher reaction speed: the voltage regulation is completed within 20ms.
When equipped with appropriate accessories, voltage stabilisers become very complete solutions and can significantly improve the power quality of the systems installed downstream.
Voltage stabilisers can be equipped with the following options:
When enriched with these optional features, a voltage stabiliser is called "line conditioner", like 3200kVA Sirius Advance shown in the picture.
Since voltage stabilisers are not equipped with any energy storage system, of course they cannot cover interruptions. Short ones have traditionally been solved by means of expensive and sophisticated equipment, such as the flywheel UPS, usually dedicated to special systems. Generators are the right solution for long-lasting interruptions.
More recently, the development of power electronics and the spread of batteries has led to the emergence of UPS as the solution for a large part of the voltage problems, which is especially true for the more complete versions ("online” or “VFI" types):
Therefore, it would look like the voltage stabiliser is destined to be inexorably replaced by the UPS. It would seem that when the designer or the person in charge of the plant decides to use a UPS, the stabiliser will automatically be discarded. But this is not always the case.
First of all, the perfect equipment without "weak points" does not exist: in the case of UPS, the most expensive and delicate aspect is the cost of the batteries on board and the fact that they have a limited useful life, after which they must be replaced, otherwise the UPS will prove ineffective.
The batteries must be carefully managed and maintained in order to optimize their life: attention must be paid to their operating temperature, but other aspects can also be annoying, for example the operation of the UPS with too low mains voltage. In fact, if the mains voltage exceeds a certain range, the UPS goes into battery operation even if the mains is on. For these reasons, some UPS are equipped with a stabilisation stage to preserve the batteries.
In Ortea we have come across many examples of synergy between stabilisers and UPS, especially when it comes to large installed power, and when the user loads include sophisticated machinery, sensitive to power quality issues. This is particularly true in those Countries, where large and technically advanced industrial plants are supplied by much less robust and solid electrical networks.
Let's see the three most typical situations.
In series
As already understood in the previous paragraph, a rather frequent synergistic use of stabiliser and UPS is to install the two units in cascade, with the voltage stabiliser immediately upstream of the UPS. In power grids where large and frequent voltage fluctuations are expected, the stabiliser in series with the UPS preventes the wear and tear of the batteries, which would normally be required to work overtime, with a significant reduction in their useful life. In this case, the stabiliser and the UPS necessarily have the same size. The stabiliser is designed to manage very large voltage fluctuations, which differ even up to 30% from the nominal value. For such situations we have supplied voltage stabilisers up to 1.5MVA.
In parallel
To ensure continuity of operation to the powered systems in the event of the UPS being out of order for maintenance or failure, a by-pass line is very often provided. If the network is unstable, but the customer does not want to add a redundant UPS, a good solution is to install a voltage stabiliser or a line conditioner on the by-pass line, thus raising the power quality at a reasonable cost for the limited period of time in which it will be called to operate. The stabiliser/line conditioner is an excellent solution for this kind of application, as it requires very limited maintenance during inactivity periods. Also in this case the two units are substantially the same size.
Centralized stabilizer, distributed UPS
A "centralized" stabiliser/line conditioner of great power associated with small "local" UPS only on the loads that really need them is an excellent solution for those systems, which are characterized by a large installed power, in order to avoid installing a huge UPS or many of them when the loads are numerous. In this case, the stabiliser brings the general power quality of the system to a good level, preserving the batteries of the individual peripheral UPS "pampering" particularly sensitive loads. On large systems this philosophy can lead to significant savings also in terms of battery maintenance/replacement. The stabiliser must be large enough to support the power of the entire system, whereas the UPS will be suited to the individual loads, to which they are dedicated. For this kind of application, we have supplied power stabilisers up to 4MVA.
The manufacturing of 6 special detuned power factor correction systems MULTImatic FH20 for a large grain milling plant in Pakistan has been completed.
Each unit has a rated power of 685kvar/415V. They will be coupled in a master-slave configuration, to create three 1370kvar power factor correction systems for the 2500kVA MV/LV transformers powering the production plant.
The plant includes numerous inverter motors, which means high current harmonics . But thanks to the robust detuning chokes on board the MULTImatic FH20 (Fd = 180Hz), there will be no overload problems on the capacitors, nor of resonance in the LV power grid.
It is interesting to underline that, in addition to the "classic" power factor control and management functions, the RPC8BGA regulator on board the MULTImatic system performs several additional advanced functions, such as the measurement of the electrical parameters and of the Power Quality (calculation of the current and voltage THD and the relevant graphic representation). These functions can be remotely monitored through MODbus protocol (on RS485 or via TCP/IP) or with Profibus protocol. The regulator can also be connected to the system in the configuration with 3 current transformers: in this case it is an "additional" multimeter. Moreover, it can monitor the hours of operation and issue warnings that recall the execution of maintenance: an important feature to keep the power factor correction system always efficient and in perfect running order
Industrial electrical systems have their own life: after they are born, they usually grow with substantial changes compared to the initial project.
The reasons can be many:
Therefore, it becomes sometimes necessary to modernize/replace/expand the power equipment located in the electrical substation, where spaces are rarely abundant and do not always allow for the installation of new heavy and big machinery.
Sometimes companies are forced to renounce interventions that would be profitable, simply because there is not enough space in the electrical room. Sometimes expensive extension works must be planned, perhaps over a long period, losing precious time in terms of efficiency and savings.
The customer is a large industrial laundry, specialized in sanitizing workwear also in the health sector, a subject of great sensitivity and urgency in this particular moment.
To improve the energy efficiency and Power Quality of their system, a 315kVA ENERSOLVE equipment was proposed and selected, but there was not enough space in the electrical room. Energy efficiency is a rather recent technology and existing electrical systems are often unprepared for housing them.
Ortea engineers have found a solution to this critical issue by proposing the equipment in IP55 configuration for outdoor installation, giving the customer the possibility to install it outside the room under a canopy.
In addition, since the power factor correction system of the laundly was obsolete, the ENERSOLVE equipment has also been equipped with an integrated 70kvar automatic power factor correction system.
The entire intervention benefits from the reduced taxation of Industry 4.0.
The whole ENERSOLVE range can be equipped with an integrated power factor correction system and it can be supplied in IP54/55 configuration for either indoor installation, for “difficult” internal environments, or for outdoor installation.
The isolation transformer is an important element for the power quality of a LV system.
Installing an isolation transformer upstream of your network allows you to galvanically isolate the loads connected downstream of the transformer from everything upstream and, consequently, to protect them from disturbances affecting the mains, in particular transient overvoltages and conducted disturbances.
Isolation transformers are used in telecommunication systems, data centers, sensitive applications in terms of security for the community, such as military bases.
In those cases where the continuity of operation of the isolation transformer is a decisive factor, monitoring and, consequently, the communication of the parameters allowing to evaluate its state of "health" become relevant.
The following example relates to a transformer supplied to a State agency in the Gulf area.
We proposed and built a transformer equipped with:
This solution will allow the customer to monitor the status of the transformer and to receive real-time information on the status of its accessories and alarms, in the event of phenomena outside its operating range.
A solution by Ortea for a very demanding customer!
The production of static stabilisers ODYSSEY is proceeding apace. The ODYSSEY has been in production for some years now and it is establishing itself on the world markets, thanks to its outstanding technical characteristics and quality, which have always distinguished all our products.
When response speed becomes an essential requirement, for example for computers, laboratory equipment, test benches, medical instruments, CNC machines, etc., the static stabiliser is a must.
Our static stabilisers ODYSSEY are available for powers from 80kVA to 4000kVA, with input voltage range ±15%, ±20%, ±25% and ±30%.
The compensation of the input voltage fluctuation is managed by exploiting the double-conversion technology. The traditional regulating system is replaced by the converters, that generate the necessary voltage once the control system has detected an incorrect situation.
The main feature of such configuration is its fast response (<3msecs), which guarantees real-time correction and voltage steadiness on the load side.
The double conversion technology also ensures insulation from disturbances and distortions in the grid. Thanks to suitable electrolytic capacitors, high power loads demands can be met.
A 10” multilingual touchscreen on the front door works as user interface. By surfing the available menus, all electrical data can be monitored and setting parameters can be adjusted.
The interface is equipped with an Ethernet communication port, allowing remote monitoring via a dedicated «client» (on request). Communication with the control system can be established also via RS485 serial bus and Modbus TCP/IP protocol.
Ortea, global supplier of Power Quality solutions, is happy to announce the signing of a cooperation agreement with Grenke, a leading Company specialized in the operational leasing of capital goods and business solutions.
The agreement, immediately operational, will allow our customers to enjoy our products with the benefits of operating rental, without immediate outlay of money and without affecting their credit lines.
This proposal is applicable to all our product lines.

Two voltage stabilizers SIRIUS ADVANCE 3200kVA ±20% are now ready to be packed. These two units will be installed in Ghana, downstream of the MV/LV transformers of a power distribution project with generation by hydroelectric power plants.
The SIRIUS ADVANCE significantly increase the #powerquality of a system, as they combines a voltage stabilizer with a power factor correction system. Moreover, they are equipped with our total protection kit, which includes an automatic input circuit breaker, a manual by-pass with interlocked automatic circuit breaker and an output motorized interlocked output circuit breaker. All in a single device!
Everyone says they know how to make them… Ortea really makes them!
Our top-of-the-range model SIRIUS ADVANCE is available as standard from 60kVA up to 4000kVA and with different input voltage ranges: ±15%, ±20%, ±25%, ±30% adjustment.
Control and stabilisation, performed on the true RMS value, is carried out by a two-way DSP-microprocessor under the supervision of a second "bodyguard" microprocessor, operating with a software which has been developed specifically for ORTEA.
The columnar variable autotransformer with rollers (ORTEA design - without sliding contacts, which are subject to heavy wear & tear) is solid and very reliable.
The user interface is a multilingual 10” touch panel equipped with RS485 port. The display shows all the electric parameters (voltage, current, active power etc.), the information regarding the operating modes (power on; voltage regulation limits; increase/decrease of voltage regulation etc.) and the alarms (minimum and maximum voltage, maximum current, overtemperature, etc.).
A panel with the reactive power regulator RPC8BGA is installed to manage the power factor correction part. Designed to provide the desired power factor, while minimizing the wear and tear of capacitor banks, the SIRIUS ADVANCE are accurate and reliable in measuring and control and easy to install.
Here are some numbers:
The manufacturing of 2 special detuned power factor correction systems MULTImatic FD25 has finally been completed. The two units will be installed in a large automotive plant in Southern Europe, where research and development activities for special tires are carried out.
The systems, each with a power of 750kvar/400V, have been fully tailor-made, in order to faithfully reproduce the two previously installed units they will replace.
Thanks to the indestructible bimetallized paper capacitors and the robust detuning reactors on board the MULTImatic FD25 (Fd = 180Hz), the harmonic currents of the system will not be a problem!
In fact, current is often affected by distortion in industrial plants. This can cause two types of problems:
To overcome these problems, detuned power factor correction systems are used. The detuning reactors installed on board must also be of excellent quality, as well as the capacitors. Our reactors are designed and manufactured by ORTEA, to guarantee the quality and reliability of the finished product. The reactors are calculated to obtain a detuning frequency of 180Hz.
When dealing with "big" stabilizers, such as these two 3200kVA SIRIUS, also their dimensions and weights are "big": each box measures 6500x2160x2770mm and weighs 14.600kg. As a consequence, also the loading operations require the use of extra-large cranes.
Since we are talking about numbers, here are those relating to these two 3200kVA SIRIUS with ± 20% input voltage range:
• Power rating: 3200kVA \ • Input voltage: 400V ± 20% \ • Output voltage: 400V ± 0.5% \ • Rated current: 4619A \ • Max input current: 5774A \ • Dimensions: 6200x2000x2400 mm \ • Weight: 12.600 kg
Our top-of-the-range model SIRIUS is available from 60kVA up to 6000kVA and with different input voltage ranges: ±10%, ±15%, ±20%, ±25%, ±30%, +15/-35% and +15/-45%.
The stabilization, performed on the true RMS value, is carried out by a two-way DSP-microprocessor under the supervision of a second "bodyguard" microprocessor, operating with a software which has been developed specifically for ORTEA.
The columnar variable autotransformer with rollers (ORTEA design - without sliding contacts, which are subject to heavy wear & tear) is solid and very reliable.
The user interface is a multilingual 10” touch panel equipped with RS485 port. The display shows all the electric parameters (voltage, current, active power etc.), the information regarding the operating modes (power on; voltage regulation limits; increase/decrease of voltage regulation etc.) and the alarms (minimum and maximum voltage, maximum current, overtemperature, etc.).
Supply of 11 x ICAR MULTImatic FH20 detuned automatic power factor correction systems of 420kvar each at 400V and 9 x fixed MICROfix FH20 power factor correction systems of 50kvar each at 400V, for a total of 5070kvar.
The customer is a large logistics facility (over 150,000 square meters with 130 loading bays) specialized in the "luxury" market, located on the outskirts of Milan, a city where luxury is at home…
Big power plants (about 12MW installed) with great attention to safety, given the peculiarity of the "treated" goods.
The loads are mainly new generation lighting, inverter air conditioning, electronic equipment: all heavily distorting loads, requiring robust detuned power factor correction systems, such as the MULTImatic FH20, which are characterized by a detuning frequency of 180Hz, thanks to the generous dimensioning of their harmonic current detuning chokes.
Power quality is crucial to guarantee absolute continuity of service to this kind of plants. And this goal is not easy to reach: the huge total length of the cables and the consequent voltage drops, the sensitivity of many users, harmonic currents … all issues that must be kept under control. Detuned power factor correction sytems avoid the risk of resonances, which could cause an amplification of the #harmonics, with a consequent deterioration of the power quality.
The customer is a major player in the fertilizer industry, located in the Po Valley.
In August 2018 a 1600kVA energy optimiser ENERSOLVE was installed at their production facility on the TR3 transformer line. Since it was installed, it has generated over 175,000kWh of energy savings, equivalent to over 15 tonnes of oil and approximately 70 of Co2.
The customer, satisfied with the excellent results obtained so far, has decided to purchase two other ENERSOLVE units of 1250kVA and 1600kVA respectively, to be installed in association with his TR1 and TR2 transformers.
Our ENERSOLVE team, as usual very attentive to saving, has decided to split each unit into two parts to minimize the installation costs and maximize the customer's ROI. This peculiar configuration will allow an easy installation, without carrying out costly structural modifications of the customer’s building.
The commissioning of a sag compensator Oxygen 320-10-40 has been completed.
This model is able to compensate for voltage sags up to -40% and to regulate in real time voltage fluctuations within ±10% of the rated voltage: all this for a power of 320kVA at 400V 50Hz.
The end customer is a multinational company specialized in the production of large-scale gas turbines, perfectly reproducing models that are no longer in production, even from third-party manufacturers. This great engineering capacity allows generating plants to be kept alive which otherwise should to be rebuilt.
The newly installed Oxygen will improve the Power Quality of a busbar, to which machines performing high-precision and long-lasting mechanical works on large and costly pieces are connected.
This new Oxygen will be added to a 250-10-40, which has already been appreciated for the excellent results obtained since it was installed at the beginning of 2019.
In addition to standard production, ORTEA SpA can design and manufacture tailor-made equipment in a short time and at low cost.
Like this 2500kVA voltage stabilizer SIRIUS with ±15% input range, designed to improve the power quality of a residential complex under construction in Myanmar.
The stabiliser has been split into two parts easy to connect, to allow handling and installation in a "difficult" environment.
This supply includes 6 power factor correction systems MULTImatic FH20 of 460kvar each at 400V, for a total of 2760kvar.
The plant is a large building used as an advanced logistics platform, one of the largest in northeastern Italy (almost 200,000 m2 covered, of which 140,000 m2 for robotic storage, 65 loading bays).
The installed power is huge: 8MW, a value that makes you think more of an industry than a logistics site!
The loads include new generation lighting, inverter air conditioners, electronic equipment, robotic handling systems: heavily distorting loads, which make it necessary to use heavy duty power factor correction systems with detuning chokes, such as the MULTImatic FH20, which are characterized by a tuning frequency of 180Hz, thanks to the generous sizing of its detuning reactors.
Power quality is essential for guaranteeing absolute continuity of service to this kind of plants. And this is not easy to obtain: the huge total length of the cables and the consequent voltage drops, the sensitivity of many users, the current distortion… issues that must be kept under control. A detuned power factor correction system helps to avoid the risk of resonances, which could cause an amplification of the #harmonics, with a significant deterioration of the power quality.
And all with an eye on energy efficiency: the whole plant is certified "BREEAM Very Good" … also thanks to the ICAR power factor correction system.
Milan, Italy (September 1, 2020)
ORTEA SpA, a leading global supplier of power quality devices, announced today the signature of a definitive agreement for the acquisition of the Assets from POWERSINES Ltd, a leading company in the market of Voltage Optimization and Energy Saving.
The production of the product lines will be based in Ortea’s manufacturing plant in Italy. The deal is effective immediately and is expected to be completed by September 30th. Upon closing, Powersines will continue to provide a service support to Ortea.
“We are pleased to bring this acquisition to completion in such a positive manner. It has been quite a long road, but with hard work and efforts by many of POWERSINES Ltd. and ORTEA SpA employees we have been able to reach a positive conclusion. We believe that this combination of our technologies and products will position us to return exponential value to our shareholders over the coming fiscal years with a larger and synergic technology portfolio to cover a larger market segment along a better integrated value proposition for our customers” stated Massimiliano Scarpellini, the Company’s Chief Executive Officer. “Furthermore, this deal will improve our EBITDA and net financial position to benefit our additional investments” continued Mr. Scarpellini.
Big currents (max input current 5774A) involve the production of extra-large components: big bars, big transformers, big regulators… ultimately: big voltage stabilizers.
Like these two 3200kVA SIRIUS with ± 20% input voltage range, intended to improve the power quality of a large Nigerian bank.
These are some numbers:
The SIRIUS, ORTEA’s top-of-the-range model, is available from 60kVA up to 6000kVA and with different input voltage ranges: ±10%, ±15%, ±20%, ±25%, ±30%, +15/-35% and +15/-45%.
The control and stabilisation, performed on the true RMS value, are carried out by a two-way DSP-microprocessor under the supervision of a second "bodyguard" microprocessor, operating with a software specifically developed for ORTEA.
The columnar variable autotransformer with rollers (ORTEA design - without brushes, which are subject to heavy wear & tear) is solid and very reliable.
The user interface is a multilingual 10” touch panel equipped with RS485 port. The display shows all the electric parameters (voltage, current, active power etc.), the information regarding the operating modes (power on; voltage regulation limits; increase/decrease of voltage regulation etc.) and the alarms (minimum and maximum voltage, maximum current, overtemperature, etc.).
Commissioning of an ICAR MULTImatic FD25/S 1500kvar power factor correction system installed in a large metal forging company. The new panel corrects the power factor of one of the largest presses in Italy (16,000ton), and is associated to a 1200kvar MULTImatic FD25/S, correcting the power factor of the manipulator (capable of handling pieces up to 100ton).
The press and the manipulator are very fast, but the two systems are able to timely correct the power factor, thanks to their thyristor switches: together, they are able to deliver almost 4000A in less than 100ms, without generating annoying transients for the system.
Thanks to this important power factor correction, the transformers powering this section (4x3150kVA) are relieved of the "effort" of carrying all the inductive reactive power needed by the motors on board the press and by the manipulator, thus reducing the thermal and mechanical stress.
The indestructible bimetallized paper capacitors of these two panels are very much appreciated in this "heavy industry" environment.
Power factor correction: an excellent solution to improve the energy efficiency and power quality of industrial plants.

Thanks to the technical characteristics of its columnar voltage regulators, ORTEA is able to design and manufacture high power voltage stabilisers (up to 6000kVA at 400V).
The quality and reliability of her equipment has enabled ORTEA to secure numerous orders; in particular, several XXL stabilizers were produced in October: on the right side of the picture we see 3 units of 1250kVA with bypass and automatic circuit breakers, and two of 800kVA for a total power of over 5MVA, ready to be shipped in Africa and North America.
Everybody boasts they can do this … ORTEA really manufactures them!
Three SAG compensators OXYGEN (for a total power of 800kVA), destined to one of the most important European International Airports, are currently being tested in our laboratory. On customer’s request, the cabinets are painted yellow, a color that does not go unnoticed. Once installed, they will provide an important contribution to the Power Quality efficiency of the hub facilities, by counteracting the effects of voltage SAGs.
On October 9th, in cooperation with Company Richard Equipment, a trade seminar about ORTEA stabilisers was held at the Hotel Casino Du Port in Dakar, focusing on our "cost-effective" range Lyra & Polaris.
The participation and involvement of the attendees was wide.
We thank our distributor Richard Equipment and our Africa Regional Director Paul-Marie Dable for making this event possible.
Being aware of the importance of ensuring qualified technical presence everywhere, ORTEA SpA keeps allocating resources for engineers training, enabling them to operate efficiently on voltage stabilisers, transformers and power-factor correction systems installed worldwide.
The first 2019 training session has just come to an end: the ORTEA team, by means of theoretical and practical learning sessions, has given detailed information to the attendees, which will allow them to maintain and repair the installed units. The participants (about thirty people in total) came from different Countries: Colombia, Egypt, the Philippines, Germany, Pakistan, Poland, Singapore, Sudan and Turkey.
The session in French will be held in September.
Modern industry is becoming more automated and the sensitivity of processes to power quality events is increasing.
It is generally recognized that quality is an important aspect of the electricity service. Not only low prices are important, also high-quality matters to customers. Price and quality are often complementary aspects; together they define the value that customers derive from consuming electricity.
Companies are more and more sensitive to Power Quality issues because they can cause troubles and damages to equipment, up to interrupting the production cycle.The most significant of all Power Quality phenomena is the voltage sag: more than 60% of poor Power Quality costs are consequence of Voltage SAGs. SAG cost is normally lower than a Voltage Supply Interruption one, but the first is by far more frequent. Troubles increase with sophisticated and electronic appliances.
WHAT ARE VOLTAGE SAGs
Temporary reduction of the Voltage RMS below a specific threshold at an electrical supply line point.
Voltage SAGs are generally caused by faults in the public network or in the installations of network users, in few cases by transient overloads due to the gearing up of large motors or the switching on of large loads. Voltage SAGs are unpredictable and random.
SAG starts when Voltage goes lower than 90% of nominal value and ends when voltages resume above 90%. Voltage SAG duration is considered within 10ms up to 1min.
The great deal of Voltage SAG has a duration lower than 1 second and a residual voltage higher than 40% of the rated value.
The voltage SAG propagates from the higher voltage levels to the lower ones, the load is often connected to a voltage level lower than the point of failure. Faults in the network cause deep voltage SAGs if they occur near loads. The incidence of voltage SAGs is much greater in the case of an aerial MV network than with underground cables.
RELEVANCE OF VOLTAGE SAGs
The more modern the equipment is and the more electronics is required, the more serious are the problems caused through voltage SAG. With the increasing number of regenerative energy sources, energy sags, fluctuations and frequency deviations also increase.
Example of costs due to voltage SAGs:
VOLTAGE SAG SOLUTION
Many businesses require immunity to voltage SAGs and voltage conditioning rather than battery back-up power, provided by UPS system. In those cases where back-up power is unnecessary, a sag compensator provides superior protection and additional power quality functions, such as protecting against SAGs, over/under voltage, voltage fluctuations.
Moreover protecting a whole plant by UPS, which can guarantee SAGs immunity, may be very costly, due to battery and maintenance costs.
The right solution is the sag compensator, that permits SAGs correction up to -50% for 1 min.
It’s an economical solution: no maintenance and operation costs: no battery energy storage required and efficiency >98% at nominal power.
Power Quality is gaining increasing attention in the electric power industry. The consumer of electrical energy requires electric power with a certain quality, but loads can have a negative impact on the electrical system and are thus also subject to an assessment in terms of quality. Power quality is therefore intrinsically linked to the interaction between the electrical system and loads and must take into account both the voltage quality and power quality.
Possible consequences of low power quality that affect business costs are:
Interruption of production due to these impacts of low power quality entails high costs due to production loss and the associated waste. For the Industrial sector, the estimated costs due to poor power quality represent 4% of turnover (Source: Studio Leonardo Energy). The impact of production interruptions is greatest in companies with continuous production.
Among the main causes of poor power quality in low voltage are:
The solutions vary for each cause. The voltage sags can be eliminated with a sag compensator, which ensures a voltage output at a nominal value. Reduced productivity, loss of data, loss of security, and machine breakdowns are only some of the problems caused by an unstable power supply that can be solved with a voltage sag compensator.
Harmonic pollution is caused by large amounts of non-linear consumption (from inverters, soft starters, rectifiers, power electronics, non-filament lighting, presses, etc.). Such devices deform the electrical current causing disturbances and problems to the system. Harmonic pollution is solved by active filters that are capable of eliminating the current harmonics in the system by measuring and injecting the same current, but in the opposite phase.
Excessive reactive power is regulated by a power factor correction system, which not only avoids any penalties due to excessive reactive energy, but reduces the “unnecessary” electrical current that flows into the lines and power components, yielding substantial benefits, such as reducing voltage drops along the lines and leakages due to the Joule effect.

Loads operated by electronic devices are increasingly adopted in more and more industrial and commercial applications such as: Variable Speed Drives, rectifiers, UPS systems, DC power supplies, welding machines, computers, TV, energy efficient lamps, photocopiers.
These loads generate waveform distortions that become threat for network components.
In particular voltage and current harmonics, where the latter is the more dangerous, generate a series of problems, like:
These effects are seldom related to harmonic current and voltage distortion, while effective remedy for harmonics are passive and active filters. Active filters achieve much higher levels of efficiency in harmonics cleaning the first does not:
