Arc simulation under overvoltage in switchgear has great significance to its design and retrofit. This article simulated the thyristor switched capacitor in transformer substation by EMTDC/PSCAD, in which, different way of restrike was considered and overvoltage waveform was obtained. The arc model based on Mayr-Cassie model is estab- lished in MATLAB/Simlink. Through the simulation of different way of overvoltage, the voltage curve, current curve of arc is obtained. The simultaneous result shows: the model could reflect the external character of arc restrike under overvoltage.
