Superconducting Fault Current Limiters (SFCL) are a new equipment for electric power industry. SFCL provides ultrafast response to short-circuit current and high efficiency of current limitation. SuperOx possesses design and production facilities for SFCLs of various voltage classes ranging from 1 to 220 kV.

Today, SuperOx holds a leading position in technology of high voltage SFCLs.

Mnevniki

In 2019, first Russian 220 kV HTS SFCL was commissioned by UNECO grid company and put into permanent operation at the “Mnevniki” electrical substation in Moscow. In 2020, HTS SFCL limited four short-circuit currents, confirming its design characteristics. Today the device is the most powerful SFCL operating in the electrical grid – worldwide.
