  • Abstract
    Post-arc current measurements were made on a high-voltage SF6 circuit breaker. A pyrotechnic device was used to protect the measurement shunt. The tests, performed at high current values between 40 and 63 kA, gave post-arc current levels of 0.5 to 2 A. Interpretation of the experimental results by the generalized Mayr model led to the determination of a set of parameters characteristic of the apparatus tested, thereby making it possible to find the test results and, in particular, to forecast cases of thermal failure
