WB2670A withstand voltage tester is a test instrument used to measure the power frequency voltage and withstand voltage test of electrical equipment. It is usually used to test the insulation performance and withstand voltage performance of electrical equipment.
The withstand voltage tester can be called an electrical insulation strength tester, a dielectric strength tester, etc. according to its function. Its working principle is: a voltage higher than the normal working voltage is applied to the insulator of the device under test for a specified period of time. The voltage applied thereto will only produce a small leakage current, and the insulation is good.
