It checks the insulation resistance of cables, motors, and electrical equipment. What voltage ranges are used in insulation testing? Typically 250V, 500V, 1000V, or 5000V, depending on the equipment rating. What does a low insulation reading mean? t means insulation damage or moisture, which could cause leakage current or short circuit. How often should insulation be tested? At least once a year or during major maintenance. What’s the safe insulation resistance value? Generally above 1 MΩ per kV of operating voltage.
