SYSTEMS AND METHODS FOR DISCRIMINATING DC ARCS AND LOAD SWITCHING NOISE

PROBLEM TO BE SOLVED: To provide systems and methods for detecting arcing in DC power systems that can differentiate between DC arcs and load-switching noise.SOLUTION: Systems and methods determine, within a plurality of predetermined time intervals, at least a pulse count (PC) per predetermined time interval and a pulse duration (PD) per predetermined time interval. The PC and the PD correspond to the number and the intensity of potential arcing events in a DC power system, respectively. The systems and methods process the PC and PD using one or more arc fault detection algorithms, thereby differentiating between DC arcs and load-switching noise with increased reliability.
