The Problem with Humidity in sf 6 Gas-Insulated Systems

The amount of water the gas can absorb depends on the temperature of the gas. At fixed conditions, the amount of water molecules going to and from the H 2 O layer to the gas is in a dynamic equilibrium. As the gas temperature increases, more water molecules pass to the gas until a new equilibrium is reached.
