Abstract :
This paper deals with the problem of single phase-to-ground fault location in distribution networks. A novel method is proposed that overcomes the difficulties that traditional fault location methods have, like their sensibility to the large transition resistance due to the fault. First, correlation is used in combination with the wavelet transform to analyze the series of transient electric wavefronts generated by the fault. Then, the travelling wave principle is applied to determine the distance between the busbar and the fault location. Theory analysis and ATP simulation indicate that the proposed method is robust and accurate.
