In the past, PI testing was all about taking a standard insulation resistance test at 60 second and again at 10 minutes. It was an accepted fact that the 10 minute value should exceed the 1 minute value by a factor of two, or more. IEEE recognized that changes motor insulation required a more in depth test. See more The applicable standard for the test is IEEE 43, which was updated in 2000 and in 2015. Prior to that, things were simple. A standard insulation resistance test was taken, observing the resistance of the insulation at 60 … See more With so many variables to consider, applying the PI test has become more like diagnosing a rash than taking a temperature. It is not therefore best applied as an actual … See more In summary, without getting overly technical, here are a few tips your motor shop should observe in applying the test in the field, or in the shop. 1.

Polarization index value is the ratio of insulation resistance (IR) for 0min to insulation resistance for min. It varies from 5-7 for new motors and should be more than.5 for a motor in excellent condition. The applied voltage should be maintained constant for 10 minutes.
