  • "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.
