Instruments Transformer

Cast resin insulated Instruments transformers for distribution networks and for special applications such as current transformers with rated nominal currents up to 3.000A, ring type transformers with rated primary currents up to 20.000A and voltage transformers with insulation level phase-to-earth and phase-to-phase up to 36 kV.

The available accuracy classes are from 0,5 to 0,2s for measuring purpose. Protection voltage and current transformers are available with accuracy class from 5P10 to 5P30 (current transformers) and 3P-6P (voltage transformers). Special current transformers for differential relay protection are available on request
