At present, electrical equipment (such as transformers, generators, etc.) is developing towards large capacity, high voltage, diversified structure, and sealing. This requires the insulation resistance tester to have the characteristics of large capacity, strong anti-interference ability, diverse measurement indicators, accurate measurement results, simple and fast measurement process, and easy portability.

The KD50A high-voltage insulation resistance tester has 8 voltage output levels, including 50V, 100V, 250V, 500V, 1.0kV, 2.5kV, 5.0kV, and 10.0kV, and can test up to 10T Ω. Large capacity, strong anti-interference, synchronous display on LCD screen, dual-use of AC and DC, simple operation, automatic calculation of various insulation indicators, absorption ratio, polarization index, and various measurement results with anti power failure function. It is a testing instrument used to measure the insulation resistance of large capacity transformers, transformers, generators, high-voltage motors, power capacitors, power cables, lightning arresters, and other devices.
