sf6 switchgear REFILLING equation in substations

Maximum gas leakage rates are typically specified as being not greater than 1% per annum in order to ensure adequate gas retention within the anticipated maintenance periods of the circuit breaker. Low gas density alarms are usually fitted to give indication of loss of gas and, in the event of rapid loss of gas, circuit breaker immediate tripping or trip lockout systems are usually employed.
