Abstract
An arc fault in an electrical circuit is detected by recording phase plane plot data of current versus voltage for at least one electrical cycle of an alternating current signal, and applying a phase plane plot arc fault monitoring algorithm to the phase plane plot data to determine whether an arc fault is present. An arc fault detection algorithm and an arc fault confirmation algorithm are employed to detect and confirm the presence of series and parallel arc faults in a circuit.
