Abstract
A vehicle, arc fault protection device of the vehicle and a method for mitigating an arc fault in an electrical system of the vehicle. The arc fault protection device includes a sensor, a switch, and a processor. The sensor is used for measuring a current in an electrical system. The processor is configured to determine a precursor phase of an arc fault from the current, wherein the precursor phase indicates an onset of an arc flash phase of the arc fault. The processor opens the switch to mitigate the arc fault during the arc flash phase.
