Explain the process of performing a dielectric withstand test (hi-pot test) on a distribution cable and interpreting the results.

A dielectric withstand test, also known as a hi-pot test, is performed on distribution cables to verify the integrity of their insulation. It involves applying a high-voltage AC or DC signal to the cable and measuring the leakage current. The process starts with isolating the cable from the system and ensuring it is de-energized. Proper Lockout/Tagout (LOTO) procedures must be followed. The cable should be visually inspected for any signs of damage. The hi-pot tester is then connected between the co....
