N2 - Partial discharges (PD) in the insulation of power equipment have been a focal point in the field of electrical technology. Numerical simulation of PD is an important approach to knowing the PD mechanics. In this paper, the physical model of PD in voids was modified and the simulation circuit of PD in voids was built using Simulink. The simulations of the epoxy resin samples with a single void and double voids were investigated, respectively. The discharge voltage waveforms, discharge current waveforms, and the single discharge waveforms of voids were obtained by simulation. At the same time, we measured the PD pulse waveforms of epoxy resin samples in time-domain by an ultra-wideband PD measuring system. The test samples enclosing artificial voids have the same size as the simulation samples. The single discharge waveforms of a single void and double voids obtained by simulation are very similar to the measured ones in the same condition. Moreover, the different discharge rules between one void and two voids are found by simulation. The conformity of the simulation results and test ones indicates that the simulation model is effective and the simulation results are reliable.
