Insulation Resistance Testing (Megger Test) for Transformers

Introduction Insulation resistance testing, commonly known as the Megger test, is an essential procedure for assessing the quality and reliability of electrical insulation in transformers. This test helps in detecting insulation deterioration that could eventually lead to transformer failures. It’s a non-destructive method that verifies the integrity of insulation between various transformer windings and from […]
