Measurement of Insulation Resistance :-

Measures the insulation resistance of HV & LV winding with respect to earth (body) and between LV & HV winding. Recommended Values are 2000 Mohms for HV and 500 Mohms for LV.

Equipment Used :- Insulation Tester or Megger.

Insulation Resistance Test or Megger Test of Transformer-

Insulation resistance test of transformer is essential type test. This test is carried out to ensure the healthiness of the overall insulation system of an electrical power transformer.

Procedure of Insulation Resistance Test of Transformer-

  • First disconnect all the line and neutral terminals of the transformer.
  • Megger leads to be connected to LV and HV bushing studs to measure insulation resistance IR value in between the LV and HV windings.

  • Megger leads to be connected to HV bushing studs and transformer tank earth point to measure insulation resistance IR value in between the HV windings and earth.

  • Megger leads to be connected to LV bushing studs and transformer tank earth point to measure insulation resistance IR value in between the LV windings and earth.
