Current Transformer TGFМ-110

The TGFМ-110 current transformer, manufactured by Electroapparat, has been in production since 1926, with the SF6-insulated model available since 1998 for 110 kV applications. Modernized in 2008, the TGFМ-110 features improved transport reliability and increased protection against improper installation. It operates effectively at low SF6 pressures and temperatures down to -55°C without gas mixtures. The transformers also include digital converters according to IEC 61850 standards for GOOSE message transmission via fiber optic channels.
