  • Power factor testing of high-voltage SF6 circuit breakers

    At the time of production, SF6 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.
