    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 sf 6 gas circuit breakers is synthetic, which have no capacitor characteristics and have no ability to absorb moisture.
