  • A Complete Strategy for Conducting Dynamic Contact

    Abstract—Dynamic contact resistance measurement (DRM) is known as an effective technique for assessing the condition of power circuit-breaker (CB) main contacts and arcing con- tacts. In some SF 6 gas CBs, the metallic fluorides (white or gray powder) produced during the arc quenching process mask the actual breaker contact resistance.
