Abstract:Accurate identification of early-stage cable faults is a necessary prerequisite for timely elimination of fault hazards. This article proposes a method for power cable fault diagnosis using wavelet transform and CNN-Informer, which can accurately identify early-stage cable faults from overcurrent signals caused by constant impedance faults, capacitor switching, and excitation inrush currents. The method extracts features from the overcurrent signals using wavelet transform and then constructs a CNN-Informer ne… Show more
