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

    circuit breaker SF6 leakage (lbs), and 3) the number of years that circuit breaker has been in operation. Specifically, three leak rates (as a percent of nameplate capacity) were estimated. The first analysis generated a lower bound, or best case scenario, of an average circuit breaker leak rate estimate. The second two analyses both generated
