Modeling of impulse electric discharge propagation in a condensed dielectric

In the present paper, special features of electric discharge propagation in a condensed dielectric are considered. A mathematical model of growth of the discharge structure and operation of a high-voltage generator is described based on the stochastic-deterministic approach. Numerical realization of the model is used to describe quantitatively the space-time and current discharge characteristics. Results of computer modeling of the discharge propagation in a condensed dielectric are presented for the tip-plane electrode geometry. Current and field discharge characteristics are analyzed. The voltage-current characteristic of technical water breakdown is obtained. __________ Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 3, pp. 11–17, March, 2006.
