500kv electrical switchgear check for leaks

Apr 01, 2020The DC hi-pot test is normally not made for AC electrical switchgear and therefore may be considered only when AC hi-pot cannot be performed. The hi-pot testing of switchgear involves testing of the circuit breakers and switchgear buses separately. This is a major test and determines the condition of the insulation of the switchgear assembly.

  • electrical - Why is my light switch leaking electricity

    The only thing to check is if they wired the ground screw on the switch to the hot instead of the bare ground wire. Otherwise, something as simple as the way the wire was coiled in the back of the box may affect the range of the non-contact tester. – BMitch ♦ Oct 30 13 at 20:12
