abstract
For distribution feeders, several low frequencies of the current waveform exhibit modified behavior under fault conditions. Two frequencies, 180 Hz and 210 Hz, were selected for study due to strong magnitude variations associated with arcing faults. A hierarchical algorithm with adaptive characteristics is presented along with the performance results when applied at these low frequencies. The various parameters which affect the sensitivity of the algorithm are discussed. The results of the tests using recorded field data are given. Discussion is included of the effects of using a digital filter front end for the algorithm. 1988 IEEE
