Abstract

This work is devoted to the modeling of streamer discharge, propagation in liquid dielectrics (water) gap using the bubble theory. This of the electrical discharge (streamer) propagating within adielectric liquid subjected to a divergent electric, using finite element method (in two dimensions). Solution of Laplace’s equation governs the voltage and electric field distributions within the configuration, the electrode configuration a point (pin) - plane configuration, the plasma channels were followed, step to step. That shows the streamer discharge bridges the dielectric liquid gap and indicates the minimum breakdown voltage required for a 5mm atmospheric pressure dielectric liquid gap as 22KV. The initiated streamer grows and branches toward all elements that satisfy the required conditions. The electric potential and field distributions shown agreement with the streamer growth, according to the simulation development time.
