Transformer station type ST-INST

The transformer station type ST-INST is an electrical device designed for use on the ground in conditions with no methane explosion hazard. The transformer station type ST-INST is designed for operate test of switchgears, capacitor banks and transformer station working in the 3-phase mine grid with insulated star point on the transformer (system IT) of rated grid voltage of 6 or 10kV. The transformer station type ST-INST for rated power 6,3 kVA is equipped in power protections against short-circuiting, overloading, ground-fault and overvoltage.
