Who can introduce withstand voltage tester?

Withstand voltage tester is also called electrical insulation strength tester or dielectric strength tester, also called dielectric breakdown device, insulation strength tester, high voltage tester, high voltage breakdown device and withstand voltage tester. A test of applying a specified AC or DC high voltage between the live part and the non-live part (usually the shell) of an electrical appliance to check the withstand voltage of the insulating material of the electrical appliance.

Withstand voltage tester can be called electrical insulation strength tester and dielectric strength tester according to its functions. Its working principle is: if a voltage higher than normal operation is applied to the insulator of the tested equipment for a specified period of time, the voltage applied to it will only produce a small leakage current, and the insulation is good.
