Three-phase combined transformers

VAH type combined instrument transformer is three-phase transformer provided for outdoor installation. It consists of three current transformers and one three-phase voltage transformer. They are produced for 24 and 36 kV voltage levels. Epoxy resin is used as main insulation. Current transformers are at the same time the high voltage bushings. Voltage transformer is suited inside of metal tank filled with transformer oil.

VAH type combined instrument transformers are:

  • reliable,
  • simple,
