Sf6 purity analyzers in switchgears - Switchgear Content

May 20, 2020 · insulating gas gas plays a key role in switchgears and the percentage of gas purity has a direct effect on the switching. Commercially, sf6 gas is supplied in pressurized bottles or liquid tanks. The gas of these bottles has a minimum degree of purity of 99.9% and may possess the following impurities according to IEC 60376: carbon tetrafluoride (CF4) <0.03%

The Problem with Humidity in Sulfr hexafluoride 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).
