An integrate method of locating fault line under single phase to ground fault in distribution network

Based the single selection method of deficiencies on the distribution network being single-phase ground fault, this paper presents the combined approach the using of transient signal wavelet analysis method and steady-state signal comparison of the amplitude method. Thus in theoretical the method of line selection is complete. The results of the MATLAB simulation analysis show that the method is accurate and reliable to be able to select grounding line.
