What is a Hipot test?

This test, also known as the Dielectric Withstand test, is used to stress the insulation of a product far beyond what it would encounter during normal operation. High voltage is applied from the mains-input lines to the chassis of the product for a specified length of time to check the integrity of the insulation by monitoring resulting leakage current. The Hipot test is a 100% production line test and can be performed using either an AC or a DC voltage.
