  • Power factor testing of SF6 circuit breakers - Siemens USA

    Siemens does not require or advocate power factor testing of SF6 high-voltage circuit breakers, therefore you will not find it in your instruction manual. 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.
