  • Power factor testing of SF6 circuit breakers | TD

    Although power factor testing of a SF6 gas circuit breaker will not cause any harm or detrimental affects to the device, misleading results may be witnessed. Any values measured will be extremely low and many times are influenced by site specific conditions or test practices such as: Contamination on the exterior of the entrance bushings. Energized over head lines or equipment adjacent to the breaker. Placement of the test
