Locating leakage faults in low-voltage distribution system is a bottleneck of power utilities.Abnormal wiring of neutral line and earth line of user is common in real world.It could cause leakage current larger than threshold of residual current devices(RCD),leading to nuisance tripping.Since it is rather difficult to locate fault results in residual current,a large number of RCDs are put out of service,which endangers users'safety at large.Frequency characteristics of arc current induced by insulation failure have been investigated thoroughly in existing literature.However,impact of user of w...
