Abstract
A method and system are provided to detect the presence of an arc fault signal on a circuit of a power distribution system. The method and system can involve: sampling a signal measuring electrical activity on the circuit, the sampled signal corresponding to a signal strength of the electrical activity on the circuit, the sampled signal comprising a plurality of sample segments; for each sample segment, computing segment properties including a signal-to-noise ratio and a root-mean-square; generating a pattern representing a presence of any signal transition over a signal sample period for the sampled signal according to the computed segment properties for each sample segment of the sampled signal; and determining a presence of an arc fault signal based on the generated pattern and predetermined pattern(s) of PLC activity on the circuit.
