  • SF6 Leak Rates from High Voltage Circuit Breakers -

    Equipment leakage is one of the two potential sources of SF6 emissions. Leak detection surveys have noted that approximately 10 percent of circuit breaker populations may leak [2, 3], and of these leaking populations, 15 percent of the breaker leaks were minor, with repairs that could be conducted immediately,sieyuan
