Claim 7:
8. The system as defined in claim 7, wherein said arc-sensing circuit comprises:
a sensor connected to said DC bus of said photovoltaic system collecting raw signal from said DC bus;
a control unit receiving said raw signal comprising:
a processor; and
a non-transitory computer-readable medium containing instruction that, when executed by the processor, causes the processor to perform:
applying threshold Local Mean Decomposition (LMD) to extract a first set of peaks and valleys from said raw signal;
finding a first set of envelopes using said first set of peaks and valleys;
applying Windowed Local Mean Decomposition (LIVID) to extract a second set of peaks and valleys;
finding a second set of envelopes using said second set of peaks and valleys;
comparing said first set of envelopes and said second set of envelopes;
sending an output signal indicating arcing when said first set of envelopes and said second set of envelopes concurrently shown an arc in said system.
