| Abstract |
[ SF_6 ] gas circuit breakers are widely used for short circuit current interruption in EHV(Extra High Voltage) or UHV(Ultra High Voltage) power systems. To develop SF_6 gas circuit breakers, the arc resistance value is necessary to compare experimental results to numerical ones. The arc resistance value can be obtained from a breaking test with a SF_6 gas circuit breaker. The direct testing or synthetic testing facility is widely used to verify the breaking ability for SF_6 gas circuit breakers. We employed the simplified synthetic testing facility to test a SF_6 gas circuit breaker prototype. The arc resistance characteristic was measured and calculated under the various experimental conditions. This arc resistance value can be used for verifying the numerical results from arc simulation in a circuit breakers. |
