SF6 Circuit Breakers - Construction, Types and Working System. Since the gas pressure is very high, a lot of care is to be taken to prevent gas leakage at joints by providing perfect scaling. The low and high-pressure systems are fitted with low-pressure alarms and set of lockout switches which give a warning the moment the gas pressure drops below a certain value because otherwise there will be a reduction in the dielectric strength and arc ...
