Current Transformer TGFМ-220

Electroapparat started producing 220 kV current transformers in 1932 for the Svirskaya HPP – Leningrad transmission line. SF6-insulated 220 kV transformers have been manufactured since 1999. The TGF-220 model was modernized in 2008, enhancing transport reliability, installation protection, and cost efficiency. Additionally, these transformers are equipped with digital converters compliant with IEC 61850 standards for GOOSE message transmission via fiber optic channels.
