Power Frequency Withstand Voltage Tester 

Power frequency withstand voltage tester, also known as AC withstand voltage test device and power frequency high voltage tester, is a core testing instrument. It simulates 50Hz power frequency voltage of power system, applies AC high voltage higher than rated value to electrical equipment and insulating materials, to test insulation resistance and detect hidden defects, commonly known as high voltage withstand test.

Core Applications

Factory test: Insulation acceptance of motors, transformers, switch cabinets, cables, insulators, etc.Handover test: Insulation inspection before putting installed equipment into operation.Preventive test: Regular inspection of operating equipment to find defects such as aging, dampness and cracks.Applicable objects: High and low voltage motors, transformers, GIS, switches, cables, busbars, insulation tools and so on.
