Insulation Resistance and Polarization IndexThe insulation resistance is the quotient of applied voltage across the insulation divided by total resultant current at a given time.Insulation Resistance and Polarization Index of stator winding are measured using a 5 Kv Tera ohm Megger with a constant output of 5000 V DC. IR & PI measurements are taken between each phase and earth while the other two phases are shorted & grounded.
