Abstract :
A new simulation method for the post arc phase of vacuum circuit breakers is presented. This simulation is based on a particle in cell scheme using Monte-Carlo techniques. The 2D axis-symmetrical plasma sheath dynamics are correctly simulated and all plasma characteristics are taken into account. The real circuit breaker geometry can be modelled and polarity effects can thus be studied. This article presents the initial results obtained with this promising approach.
