Abstract:
1. A method for detecting electrical arcing on an electrical power system, comprising the steps of: obtaining first data indicative of the temporal behavior of a signal which is indicative of a first periodic property of the electrical power system, wherein the signal includes a steady-state load component of the first periodic property as well at least one burst of the first periodic property having a magnitude substantially greater than any steady-state load present in the electrical power system, and providing the first data to an electronic computing device; and using the electronic computing device, observing the first data at a first resolution and determining that an arcing event is potentially present on the electrical power system when the burst contained in the first data includes a peak having a precipitous decrease at its end; and if an arcing event is determined to be potentially present, using the electronic computing device to examine the first data at a second resolution finer than the first resolution to determine whether an arcing event is present; Wherein the resolution including data sampling rate.
