Frequency phenomenon and algorithms for arc detection

Successful detection of power line arcing requires various algorithms from frequency domain to time domain analysis. This paper explores frequency phenomenon that when analysed with a defined set of algorithms can distinguish between arcing noise and typical power line noise associated with distribution hardware and various noise-generating loads. These techniques may be applied to measuring conducted and radiated emissions in the electromagnetic environment. They may also be applied to H and E fields resulting from the spreading of distribution lines within a secondary power-distribution system down inside a manhole. The promising quick detection and identification from laboratory and actual field measurements is necessary and critical to ensure life-safety for manhole workers during maintenance activities.
