  • SF6 Gas Dehydration System That Doesn’t Require Downtime

    Up until recently, the only way to dehydrate SF 6 has been to take the gas-insulated switchgear (GIS) offline, evacuate the gas, pass it through a gas handling unit with dehydration filters, refill the GIS with the dried gas, and then put the system back online. This can be a time-consuming process that requires power plant downtime.
