Systems and methods of discriminating DC arcs and load switching noise

Systems and methods of discriminating DC arcs and load switching noise

Systems and methods of detecting arcing in DC power systems that can differentiate between DC arcs and load-switching noise. The systems and methods can determine, within a plurality of predetermined time intervals, at least the pulse count (PC) per predetermined time interval, and the pulse duratio...

description Systems and methods of detecting arcing in DC power systems that can differentiate between DC arcs and load-switching noise. The systems and methods can determine, within a plurality of predetermined time intervals, at least the pulse count (PC) per predetermined time interval, and the pulse duration (PD) per predetermined time interval, in which the PC and the PD can correspond to the number and the intensity of potential arcing events in a DC power system (100), respectively. The systems and methods can 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. Fig. 2
