WebbThe HIPOT test is a dielectric breakdown threshold test and not intended to test line filter Y cap current at elevated steady-state voltages. It is intended to stress manufacturing process breakdown (pun intended) due to insufficient clearance gaps or lack of silicone added insulation in the process. Webb8 nov. 2024 · With DC Hipot testing, you measure the insulation resistance of cables by ohm’s law. The DC Hipot voltages value depends on the thickness and the type of the insulation, conductors’ size, and cable construction. Benefits Firstly, there is an adjustable trip option for leakage current.
