The sensed conditions are relayed to an analyzing device, the analyzing device including a current peak detector. The presence of a measured current value is determined. If the measured current value is greater than a current threshold value, a faulted circuit indicator (FCI) analysis is performed to determine the presence or absence of an FCI fault. If an FCI fault is absent, an incipient fault analysis is performed, wherein the RMS current values before and after a threshold event are compared and the voltage total harmonic distortion (THD) before and after the event are compared. If the two current values are within a first predetermined percentage and the THD values differ by a second predetermined percentage, then an incipient fault is reported.
