Transformer Test Equipments

Test instruments perform various diagnostic tests on power and instrument transformers.

  • Winding resistance measurement (IEC 60076-1)
  • Analysis of on-load tap changers (IEC 60214-1)
  • Heat run test (IEC 60076-2)
  • Automatic transformer demagnetization
  • Turns ratio measurement of power and instrument transformers (IEC 60076-1)
  • Excitation current measurement
  • Phase angle measurement
  • Transformer vector group detection
  • Demagnetization status verification
