Power factor testing of Sulfr hexafluoride circuit breakers | TD Guardian

At the time of production, Sulfr hexafluoride gas circuit breakers are subject to a high-voltage withstand test. This incorporates an AC High-Potential (Hi-Pot) test transformer capable of achieving the required high-voltage levels (per industry standards). Therefore, field Hi-Pot testing is also not necessary or required.

High Potential (Hi Pot) | Specialized Engineering Services, Inc.

The Basic test Voltage for Hi Pot testing is the 2X (Operating Voltage) + 1000 V. The reason for using 1000 V as part of the basic formula is that the insulation in any product can be subjected to normal day-to-day transient over voltages.

After component replacement, installation of new sf6 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.
