An insulation resistance (IR) test, commonly referred to as a Megger test, collects information such as insulation resistance. An insulation meter, or Megger tester, uses an applied direct current voltage to measure insulation resistance, creating a log of the condition of the insulation between two conductive parts. The higher the level of insulation resistance, the better the shape of the insulation. Megger testers enable you to document the performance of insulators, measuring resistance value and testing for leakages.
Insulation meters confirm your circuit’s reliability, especially in final checks during new equipment installations. Megger testers are a safe and effective way to test the insulation resistance of your equipment.
