  • Power factor testing of SF6 circuit breakers | TD

    Power factor testing is used for checking the capacitance level and any current or dielectric losses, designed principally around such devices that use organic insulating materials. Secondly, the test voltage level is insufficient and does not fully prove or disprove the insulation integrity of a SF6 gas circuit breaker.
