Abstract

The authors provide evidence for PD (partial discharge)-induced changes in epoxy surface resistivity and relate these changes to observed nonstationary behavior in the statistical characteristics of the PD with the aid of a Monte-Carlo simulator. The experimental results are obtained for an alternating voltage of variable frequency applied to a point-dielectric gap configuration. The stochastic properties of a PD generated by applying an alternating voltage to a point-dielectric gap are predicted using a Monte-Carlo computer simulation based on a model similar to that described by R.J. Brunt et al. (1992, 1993)
