Retrofit Instrument Transformers

Retrofit Instrument Transformers

Through partnership with Transmag (UK), GFF Power is able to offer an extensive range of indoor & outdoor current and voltage transformers.

For indoor switchboards, Transmag supply both IEC and BS designs, with particular emphasis on old medium-voltage switchboards covering:

  • Three phase & single phase voltage transformers
  • Single phase cast resin current transformers
  • Three Phase current transformers also available

For outdoor switchyards, Transmag are often able to offer a like-for-like replacement for both voltage and current transformers, either to IEC or BS, with oil or cast resin insulation. This can remove the need to replace existing metal structures.
