Power factor testing of Sulfr hexafluoride circuit breakers | TD Guardian

At the time of production, sf6 gas 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 sf6 gas gas circuit breakers is synthetic, which have no capacitor characteristics and have no ability to absorb moisture.

sf6 gas circuit breaker maintenance | TD Guardian Articles

The first generation of sf 6 circuit breakers was the lower voltage classes of 72kV and 145kV. As gaz sf6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing gaz sf6 as the line-to ground dielectric insulation.
