Abstract |
[ SF_6 ] gas circuit breakers are widely used short circuit current interruption in EHV or UHV power system. For a SF_6 gas circuit breaker development, the SF_6 gas velocity measurement is necessary during SF_6 circuit breaker's trip operation. Small-gap flashover characteristics are used for this measurement. So, small-gap measuring system which will be used to develope GCB should be developed. This study shows the characteristic analysis and experimental results of small-gap measuring system. |
