Abstract
numerical model to simulate a partial discharge within a bound cavity is presented in this paper. The partial discharge inception voltage and current pulse characteristics are established numerically and compared against experimental tests. The defect geometry used in this work is associated with a high voltage transformer bushing, namely a cavity formed between a punctured aluminium grading foil layer and the surrounding oil impregnated paper insulation.
