Insulation resistance tester (or high-voltage insulation meter) is a special instrument for measuring insulation resistance. It is an ideal test instrument for measuring the insulation resistance of large transformers, transformers, generators, high-voltage motors, power capacitors, power cables, fasteners, etc.
