... of the faulty phase(s) appeared to be smaller than the healthy phase(s). Hence, the current waveform of faulty phase(s) appeared swollen, which indicates an unhealthy system. Once the fault is removed, the current and voltage waveforms become stable. ANNs Fault detection Fault classification...
