    2020-11-30SF6 is generally used in this gas-insulated switchgear (GIS). Because it is so important to control greenhouse gas emissions, any plant containing SF6 should be equipped with monitoring systems to warn of leaks. Regular inspection is necessary, typically twice a year, which inevitably adds to the total operating costs of the switchgear.
