Influence of wavelet characteristics on single-phase grounding fault line selection
IOP Conference Series: Earth and Environmental Science, 2022 Abstract It is difficult to select the fault line in distribution network because of the small single-phase grounding fault current. Wavelet transform is especially suitable for fault transient analysis because of its unique time-frequency localization performance.
