Equivalent network modeling to simulate electrical discharges

This paper presents an integral method developed to simulate the current wa veform generated by electrical discharges in overvoltaged air gaps. The ele ctrodes/dielectric physical configuration is modeled with a schematic grid of nonlinear impedances and the resulting circuit is solved utilizing the s tandard SPICE network simulator. Different electrode geometries have been i nvestigated and experimental data have been used to validate the simulation results.
