Abstract. High-voltage circuit breakers (HVCB) generally act in pure SF 6 under pressure of a few bars. the wong of this kind of circuit-breaker consists first to create an electric arc due to the separation of the contacts and second to rapidly extinguish this arc by a high blowing during the current-zero phase of the alternative current. for a given gas, the rate of transition from the
