Simulation, Electrical Breakdown, Probability Distribution
A discrete stochastic model is proposed for the simulation of electrical breakdown in long air gaps with extremely nonuniform electric field between the electrodes. The model is taking into account the basic characteristics of breakdown in gaseous dielectrics, such as, the occurrence of streamer corona and leader. With some modifications, this model can also be used for the simulation of breakdown in small gaps. We use this model to determine qualitatively the probability distribution of the gap breakdown voltage. The determination of the failure probability distribution of an insulating gap is of great importance for the estimation of the strength of the insulation of high voltage equipment under electrical stress.
