Dielectric withstand test - Wikipedia
Voltage withstand testing is done with a high voltage source and voltage and current meters. A single instrument called a "pressure test set" or "hipot tester" is often used to perform this test. It applies the necessary voltages to a device and monitors leakage current. The current can trip a fault indicator. The tester has output overload ...
