Cable Hi-Pot (High Potential) Testing is a critical procedure used to verify the insulation integrity of electrical cables by applying a high voltage, typically much greater than the operating voltage. This test helps identify insulation weaknesses, manufacturing defects, or installation damage that could lead to failures or safety hazards. Hi-Pot testing is commonly performed during cable commissioning or routine maintenance, ensuring cables can withstand overvoltages without breakdown. It can be done using AC or DC voltage, depending on the cable type and standards. Regular Hi-Pot testing ensures system reliability, reduces the risk of downtime, and confirms compliance with electrical safety regulations.
