Detection and Identification Technique for Series and Parallel DC Arc Faults

This paper proposes a series and parallel DC arc detecting identifying (SPADI) technique using the frequency features of load current (IL) voltage (VL). The changes in VL IL under are different. can only raise high-frequency components VL. In contrast, be increased both arcs. However, increasing range is generated by concentrated 5 kHz to 40 band. Meanwhile, caused observed evenly all ranges. Inspired these features, VL’s 100 used sense proposed technique. addition, detected 50 bands IL. Experimental tests verified algorithm implemented at digital signal processor (DSP). As result 160 repeated tests, probabilities were % 96.25 %, respectively. Moreover, probability correctly type when was %. Also, average detection times 0.11 s 0.16 s,
