Abstract	For simulation of partial discharge (PD) patterns, a finite difference method (FDM) based model is put forward, in which two parameters are considered, viz. the critical field intensity for partial discharge occurrence $E_{c}$ and residual field intensity Er . In this present simulation model both partial discharge inception and extinction are taken to be stochastic in nature. The void taken in this simulation is a narrow one for which the discharge area is taken to be fixed and is equal to the area of the top or bottom surface of the void. In this paper plane-plane electrode system is considered and the PD simulations are carried out by varying $E_{c},$ considering stochastic as well as non-stochastic occurrence of partial discharge and residual field. The inception and extinction of PD, shape of PD patterns in the form of pulse amplitude and the amount of charge, which is released during PD for different cases, are studied and reported in this paper
