1. A method, comprising a plurality of activities, comprising:
- for each of a plurality of potential arcing events associated with an alternating current;
sensing the potential arcing event;
identifying an amplitude-duration pair associated with the potential arcing event;
for an amplitude-duration pair that fulfills a predetermined amplitude criterion and an associated predetermined duration criterion, assigning a score, the score one of a plurality of predetermined scores, each of the plurality of predetermined scores associated with an amplitude range of a plurality of amplitude ranges, the score selected based upon a determined range of the amplitude comprised by the amplitude duration pair;
assessing the scores for the plurality of amplitude-duration pairs; and
based on said assessed scores, determining if the plurality of potential arcing events corresponds to an arcing condition.
