Abstract
Certain exemplary embodiments can include an arc fault detection circuit. The arc fault detection circuit can include a zero crossing analysis sub-system including a counter configured to determine, for a first waveform, a count of dips that occur between a pair of predetermined zero crossings of a second waveform. The second waveform can be obtained from an electrical circuit.
