1. A system for detecting and identifying arcing in an arc fault circuit interrupter having a power-line monitoring and processing circuit comprising:
a power-line monitoring and processing circuit obtaining data indicative of line voltage and line current; and
a logic circuitry including non-transitory computer-readable medium storing computer readable instructions and one or more processors coupled to said non-transitory computer readable medium, and when executing said computer readable instructions said logic circuitry:
controls said power-line monitoring and processing circuit to obtain a first data indicative of the line voltage and the line current for a first cycle of the voltage waveform;
controls said power-line monitoring and processing circuit to obtain a second data indicative of the line voltage and the line current for a second cycle of the voltage waveform subsequent to the first cycle;
correlates the second data with the data representative of at least one known arc reference cycle;
correlates the first data stored with the second data; and
outputs a signal indicative of an arc-event when the second data correlates with the at least one known arc reference cycle within an arc-event correlation threshold, and the first data does not correlate with the second data within a previous-cycle correlation threshold.
