CALCULATION OF THE BREAKDOWN VOLTAGE IN AN ELECTRICAL DISCHARGE AT HIGH PRESSURE

Abstract

The subject of this work is the study of voltage in a discharge plasma at high pressure. The voltage is a very important parameter for industrial applications, found in the excimer lamps, plasma panels, and streamer even discharge crown. This breakdown describes the transition from state insulating gas to a state driver. We calculate the Paschen curve with an analytical resolution of the equation of self-sustained, and a fluid model 2D, which is based on the numerical solution of the two Boltzmann equations (equation of continuity and momentum), coupled to Poisson’s equation, which represents the voltage depending on the product gap spacing- pressure product for various rare gases neon, argon and krypton, xenon.
