The Problem with Humidity in insulating gas Gas-Insulated Systems

The SF 6 in the gas compartment can absorb a certain amount of water. When the amount of water exceeds the saturation point of the gas, the excess condensates and forms a water layer (if the gas temperature is above freezing) or sublimates and forms an ice layer (if the gas temperature is below freezing).

Even if the gauge is not yet in the red zone, any loss of gas should be investigated thoroughly so that the leak can be repaired before refilling.

The initial ionization potential of the gaz sf6 gas is the same to nitrogen. The size of the sf6 molecule is much higher than a nitrogen. That practicality denotes that the free path for an electron impact in gaz sf6 gas is at least a third of the path which it is in nitrogen. What’s more: Kinetic energy is considered a function of the velocity squared.
