Abstract
Partial discharge transients can be described in terms of the charge induced on the detecting electrode. The influence of the void parameters upon the induced charge is examined and discussed for spheroidal voids. It is shown that a quantitative interpretation of the induced charge requires a knowledge not only of the void location, geometry and dimensions, void gas pressure and composition, but also of the void orientation with reference to the applied field
