This essay presents a single-ended ranging algorithm based on transient basic frequency components .The fault distances can be obtained by using the frequency domain and time domain methods to get relevant solutions . The EMTP simulation results show that the maximum relative error of the algorithm in ranging is less than 0.231%and the average error is less than 20 meters,so it can meet the requirements of practical engineering .
