Station service voltage transformer TIP (72.5 – 550 kV)

All transformation ratings in one single equipment

The TIP “Station service voltage transformer” is a voltage transformer insulated in SF6 gas that combines the characteristics of a voltage transformer with power capability. The TIP has been designed for voltage up to 550 kV and with power capability up to 500 kVA.

  • MV or LV output available
  • Suitable for outdoor installations
  • The magnetic cores are made of laminated steel with oriented grain and a high level of permeability
  • The windings are made of electrolytic copper
  • The external bushing is made of composite material
  • Enclosure made of aluminum alloy
  • Remote control of the internal insulation level by means pressure gauge provided with an alarm threshold and lock threshold
  • A pressure relief device protects the apparatus from internal overpressure


  • Tap changer
  • Metering windings
  • Motor-activated disconnector
  • Circuit breaker


  • Power transformation

Why Hitachi Energy?

  • Cost-effective solution for isolated applications
  • Perfectly suited for integration with a complete high voltage switchgear bay
  • Auxiliary power supply directly from high voltage line
  • HV to LV and HV to MV direct transformation
  • High safety thanks to SF6 insulation and polymeric bushings: explosion-proof, not flammable
  • Maintenance-free
