Claim:
1. A method of detecting arcing in a DC power system, comprising the steps of: monitoring at least two current outputs by at least two current sensors, respectively, the at least two current sensors having reverse polarities, the at least two current outputs being provided for monitoring by the respective current sensors over at least two adjacent conductors, respectively, in the DC power system; combining the at least two current outputs to provide a combined current output; generating one or more pulses in response to at least one change in the combined current output over time (di/dt), the respective pulses having associated durations; processing, by a processor, the respective pulses to determine a presence of arcing in the DC power system, the processing of the respective pulses including: generating, by the processor, an output indicative of the presence of arcing in the DC power system.
