Cable hipot (high potential) testing is a method used to verify the integrity of a cable's insulation by applying a high voltage, much higher than normal operating levels. This test detects insulation weaknesses, defects, or potential breakdowns that could lead to failures. Unlike insulation resistance testing, hipot testing checks the dielectric strength of the cable. It can be performed as an AC or DC test, depending on the cable type and standards. Hipot testing is typically done after installation or repair to ensure the cable can handle operational voltages safely. It's a critical step in quality assurance and electrical safety.
