DC Hipots are essential to testing insulation resistance and maintaining proper electrical insulation function. A high voltage, several times larger than what is used in AC testing, is applied to cables (only new cables are recommended for this test). DC test voltages are more difficult to generate than AC voltages, but they offer increased performance and safety enhancements. DC Hipot testers are highly sensitive, allowing the operator to identify measurements that may have been missed when testing with an AC Hipot alone. Advanced Test Equipment Rentals carries DC Hipot testers from trusted manufacturers like Chroma, Associated Research, Vitrek, and more.
