RUSNANO’s Portfolio Company Profotech and Maxwell Technologies SA (Maxwell) Gave an International Presentation of their New Joint Product: Combined Optic-Electronic Current and Voltage Transformers

17 November 2016

Profotech and Maxwell Technologies SA (Maxwell) gave a ‘live’ presentation of their new joint product—combined optic-electronic current and voltage transformers (123 kV) at the 16th International Exhibition and Conference on Electric Power Equipment and Technology, EP China/Electrical China 2016, held in Beijing. Representatives of design, electric power, generation and engineering companies from China, India and Europe were invited to attend and discuss the product and solutions based on it.

Combined optic-electronic current and voltage transformers are a unique technology with no equivalent worldwide. They combine all the advantages of two electronic transformers in one. Their reduced size and weight compared to conventional electromagnetic transformers means that combined transformers can be installed even  in small substations where there is limited space.

This product is key in building smart networks, digital substations and serves as a single data source for all secondary smart devices.

The product is the result of joint development work undertaken by engineers and scientists from both Profotech and Maxwell. Currently, the companies produce transformers able to handle 123 kV, but are planning to release higher voltage versions in the future.

Maxwell will promote the new product on the international market.

“There is no doubt that our companies’ product will make a splash on the market of intellectual devices for smart grid networks in the near future. We can see great commercial potential for our new product. It is now even smaller, smarter, and, judging by the interest shown by Chinese and Indian energy companies at the exhibition, will undoubtedly be in demand in the near future! Profotech has already begun to expand its manufacturing output in light of the growing demand for its product,” said Oleg Rudakov, General Director of Profotech.


Profotech, JSC (a RUSNANO’s portfolio company) has been engaged in developing and manufacturing optoelectronic current and voltage transformers since 2010. Profotech is currently the only Russian manufacturer that has its own technology and a complete production cycle for this product.
