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

After component replacement, installation of new insulating gas 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.

the surrounding Sulfr hexafluoride. hot spots creating metallic vapors and excessive wearing are avoided through the motion of the arc roots. This rotation of the arc will proceed no more than half a period, until a current zero. The speed of rotation of the arc has been measured. It varies with the intensity of the current to be interrupted and can reach the speed

What is HIPOT Testing (Dielectric Strength Test)?

Mar 30, 2021 · Open circuit breakers or switches to isolate the circuit or Cable that will be hi-pot tested. Confirm that all equipment or Cable that is not to be tested is isolated from the circuit under test. 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.
