Abstract

Computation of partial discharge signal propagation along power cables with concentric neutral wires and ground plane is investigated. A distributed RLC network model of the cable is formed to simulate this phenomenon. The electromagnetic parameters of the power cable are calculated with a finite element method. Employing the three-line transmission theory, the waveform propagation in both time and frequency domain is formulated. Simulation results are presented and discussed.
