Power factor testing of gaz sf6 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. The insulating material used in the manufacture of modern insulating gas gas circuit breakers is synthetic, which have no capacitor characteristics and have no ability to absorb moisture.
