What is Insulation Resistance Testing Guide about?
The insulation resistance (IR) test measures the resistance between conductive parts of electrical equipment using a DC voltage to check the condition of insulation. A higher resistance reading indicates better insulation. Factors like temperature and humidity can affect readings, so standards provide minimum acceptable values and correction factors. The non-destructive IR test is commonly used to test equipment in the field before and after maintenance.
