Epoxy resin voltage transformers

Voltage instrument transformers are used to insulate measurement and protection equipment from high system voltage and to step-down primary voltages to defined values, and thus provide standardized, useable voltage in a variety of power system measurement and protection applications.
Whether the voltage transformer is provided for indoor or outdoor installation, different epoxy mixture is used.

Epoxy resin voltage transformers produced by Končar are:

  • indoor installation – VPA
  • outdoor installation – VPV, VLA
