ARC FAULT DETECTION AND CONFIRMATION USING VOLTAGE AND CURRENT ANALYSIS.
Application 648/DEL/2005 published 2006-11-10, filed 2005-03-24
An arc in arc electrical circuit is detected by recording phase phase 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 determined whether an arc vault 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.
