Abstract

Voids in solid insulation give rise to partial discharge (PD). Factors affecting PD activity in internal voids include the type of gas contained, gas pressure and surface properties of the void. Identifying the presence of PD and understanding the measurable parameters may allow improved management of industrial assets. This paper reports on quantifiable and measurable differences in PD activity and material degradation among voids which have vented and unvented channels. To investigate changes in PD activity with void characteristics experiments are carried out using artificial voids created from layered sections of poly(ethylene terephthalate) (PET) polymer.
