About this document
Insulation Resistance & PI Testing Guide by venkatws is a document available to read on EtoBox.
1. The insulation resistance and polarization index tests evaluate the condition of electric motor and generator windings by measuring insulation resistance over time. 2. A low polarization index indicates contamination with moisture or dirt, while a low initial insulation resistance suggests deterioration of the insulation. 3. These tests are useful for detecting issues before they cause failures, as the health of the windings largely determines the lifespan of the machine.
