Waveform characteristics of underground cable failures

In this paper unique characteristics of underground cable faults are extracted from the voltage and current waveforms recorded by power quality monitors. These characteristics are used to classify cable faults on the basis of fault duration, specific cable equipment failure and root-cause behind the fault. They are also used to distinguish underground cable faults from other overhead distribution line faults. Waveform signature analysis, wavelet transforms and arc voltage during the fault event is used for cable fault identification and classification.
