Potential transformer :-

Potential transformer is a voltage step-down transformer which reduces the voltage of a high voltage circuit to a lower level for the purpose of measurement. These are connected across or parallel to the line which is to be monitored.

Testing Procedures

  • Insulation Resistance test.
  • Voltage Transformer Ratio & Polarity test.
  • Winding Resistance test.

Equipment Required

  1. CPC 100 for VT Ratio & Polarity test.
  2. Insulation Resistance tester: Megger mit1020.
  3. Multimeter.
  4. Micro ohm meter: Drlo10

Insulation Resistance Test

  • Use Megger mit1020 to measure insulation resistance.
  • Insulation Resistance Tests to be done:
    • Primary winding – Ground      (Apply 1kV for 1 minute)
    • Primary winding – Secondary winding      (Apply 500V for 1 minute)
    • Secondary winding – Secondary winding      (Apply 500V for 1 minute)
    • Secondary – Ground      (Apply 500V for 1 minute)

VT Ratio & Polarity Test

  • Use Omicron CPC100 to test VT ratio & polarity.
  • ​Connection on CPC100 will be same as the shown figure.
  • Repeat the test for the other phases and the other secondary cores.
