  • Patent number: 11908645
    Abstract: Systems and methods for improving control of an internal arc fault in equipment. The equipment includes a bus configured to provide three-phase power from an incoming line. Furthermore, the equipment includes a current loop formed from a first conductor and a second conductor, where current is received from the bus. The current loop uses electromagnetic forces of a short-circuit current caused by an internal arcing fault of the equipment to move the first and second conductors relative to each other. In response to the movement of the first and second conductors, the current loop creates a gap between the first and second conductors where a new arc ignites at the gap. In this manner, the loop design takes advantage of the natural electromagnetic force to reduce the arc energy at the point of initiation and relocates the energy release point to an exhaust vent of the equipment.
