Arc Flash Management
WATLOW ' s new POWERSAFE™ medium voltage thermal system
Arc flash mitigation technologies Arc flash mitigation technologies ( hereafter arc mitigation ) take a different approach ; instead of redirecting the energy from the event , arc mitigation seeks to reduce the energy of the event itself by limiting its duration . This is done by
detecting the arc flash early and automatically tripping the appropriate circuit . This can be done in two ways - sensing current ( referred to as current arc mitigation ) or sensing light ( referred to as optical arc mitigation ).
