Cable Hi-Pot (High Potential) testing is a crucial method used to evaluate the dielectric strength of electrical cables by applying a high voltage to check for insulation breakdown. This test helps identify defects such as cracks, voids, or moisture in the insulation that may not be visible through visual inspection. Hi-Pot testing is typically performed during cable commissioning or after repairs to ensure the cable can safely handle its rated voltage. It includes both AC and DC methods, depending on the application. Regular Hi-Pot testing enhances system reliability, ensures safety compliance, and prevents unexpected failures in power distribution networks.
