SF? gas circuit breakers are widely used for short circuit current interruption in EHV or UHV power system. For a SF? gas circuit breaker development, the hot gas velocity measurement is necessary during SF? gas circuit breaker s trip operation. Small-gap flashover characteristics are used for tills hot gas velocity measurement. This study sho ws the hot gas velocity measurement results during SF6 gas circuit breaker' trip operation.
