  • SF6 Leak Rates from High Voltage Circuit Breakers - U.S

    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, while the remaining 85 percent were

    and above. A government prescribe annual leakage rate of 0.89% of capacity combined with handling losses suggests the case study area’s SF6 insulated equipment is responsible for 2,905 tonnes of CO2 equivalent emissions per year. Alternatives, eliminating or reducing the use of SF6 insulation in HV circuit breakers and associate
