  • "Hissing sound" in SF 6 Gas insulated HV Switch Gear

    After component replacement, installation of new SF6 gas and other repairs, re-run the Hi-Pot test to confirm that the switchgear is able to withstand voltages at least 50% greater than the name-plate rating. Of course all of this advice is worthless if the unit has already failed. Remember that a Hi-pot is actually a destructive test.

  • What is HIPOT Testing (Dielectric Strength Test)?

    Mar 30, 2021 · The limited approach boundary for this hi-pot procedure at 1000 volts is 5 ft. (1.53m) so place barriers around the terminations of cables and equipment under test to prevent unqualified persons from crossing this boundary. Connect the ground lead of the HIPOT Tester to a suitable building ground or grounding electrode conductor.
