Investigating the dependence of partial discharge activity on applied field structure

Investigating the dependence of partial discharge activity on applied field structure
Models of partial discharge (PD) activity have been used to successfully replicate PD data from experiments under controlled conditions. These experiments have typically investigated PD activity from an artificial defect, often a gaseous void, surrounded by a homogeneous dielectric material in a parallel plate electrode arrangement where the applied electric field acts in one direction. In this work PDs from gaseous voids in elliptical applied fields, found in three-phase cable joints, are modelled. PD activity was shown to be highly dependent on void location, with PDs per cycle and apparent charge magnitudes varying significantly between void locations. It was also shown that the measured apparent charge from PD is highly dependent on the direction of the discharge and the distance of the void from the measuring electrode. The limitations of the model are discussed and the improvements that will be made in future work introduced.

Abstract

Models of partial discharge (PD) activity have been used to successfully replicate PD data from experiments under controlled conditions. These experiments have typically investigated PD activity from an artificial defect, often a gaseous void, surrounded by a homogeneous dielectric material in a parallel plate electrode arrangement where the applied electric field acts in one direction. In this work PDs from gaseous voids in elliptical applied fields, found in three-phase cable joints, are modelled. PD activity was shown to be highly dependent on void location, with PDs per cycle and apparent charge magnitudes varying significantly between void locations. It was also shown that the measured apparent charge from PD is highly dependent on the direction of the discharge and the distance of the void from the measuring electrode. The limitations of the model are discussed and the improvements that will be made in future work introduced.
