NettetPolarization Index (PI) Test. A PI test reveals aged, brittle insulation and deteriorating insulation in the ground wall. For this test, the applied voltage must be kept constant for 10 minutes, and the insulation resistance is measured at 1 and 10 minutes. The polarization index is the ratio between the 1-minute and 10-minute measurements. Nettet29. mai 2024 · The whole point of testing is to subject the winding to industry standard voltages to prove or disprove insulation integrity. If the motor fails these tests it doesn’t mean that the motor will not run. It simply means that the insulation is weaker than it should be and the motor will eventually fail because of this. splitwise careersNettet30. jun. 2024 · The surge test is the only test that finds turn-to-turn insulation weaknesses in motor windings.
