Gas Insulated Switchgear leak rate abb

While all suppliers of sf6-gas equipment certify to leak rates equal to or less than 0.1%, the field leakage data over the past 15 years shows an actual sf 6 equipment have a much higher leak rate than that. The average sf6 leak rate in California is approximately 2%, which is significantly higher than the certified leak rate of 0.1%
