Epoxy Resin Cast Current Transformers

Epoxy Resin Cast Current Transformers

Epoxy Resin Cast Current Transformers
  • Current Transformers are used to step down the current from a high value (say 200 A) to a lower value (1 or 5 A) suitable for measuring instruments like ammeter, energy meters and protective relays.

Advantages Of Current Transformer

  • Provides electrical isolation between high voltage power circuit and measuring instruments
  • Reduces insulation cost of measuring instruments
  • Ensures the safety of operators
  • Reduces utility losses
  • Protects the device during fault conditions
