Abstract :
Properties of partial discharges associated with electrical treeing are briefly explained and a model is proposed. Based on the proposed model, a computer simulation was carried out by using the Monte Carlo method. It was deduced from the simulation that the tree channel length and its distribution determine the PD pattern. The PD patterns of tree initiation and tree-like trees were obtained from short and long channels with a broad distribution, respectively. Those from the bush-like trees were obtained from long channels with a narrow distribution
