Abstract
A DC arc fault device and methodology includes acquiring a signal in response to a DC current. A software module identifies a parallel DC arc event when a difference between a maximum signal value and a minimum signal value exceeds a threshold. The software module also determines average signal values over multiple selected time periods and identifies a series DC arc event in response to the difference between the average values exceeding a predetermined threshold.
