Abstract

The electrical properties of an epoxy resin system for use as machine insulation containing either ZnO or Al2O3 fillers have been investigated. The fillers impart non-linear current-voltage characteristics to the materials. The electrical conductivities of plaques of epoxy containing filler were a function of the applied electric field strength. The current-voltage relationship was dependent on the filler and differed from that for the unfilled material. The current transient as a result of an applied DC step voltage depended on the filler type and applied field strength. Multi-layer, plaque samples of mica-paper, glass-cloth and epoxy resin, with and without ZnO filler, were examined electrically. Current transient measurements allowed the estimation of the dielectric loss from ~10-5-10-1 Hz. Global thermally stimulated depolarisation current (TSDC) spectra were obtained. Partial polarisation spectra at 5°C intervals were also obtained from 35-150°C for unfilled and 20% ZnO filled samples. The spectra showed significant differences between sample types
