The Problem with Humidity in sf6 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).

Sulfr hexafluoride Gas Analysis - Qrometric

Gas Insulated Switchgear. For gaz sf6 filled gas compartments, Sulfr hexafluoride in accordance with either IEC 60376 or IEC 60480 is used. In order to prevent condensation, the maximum allowable water content is defined by a dew-point no higher than – 5 °C. Gas compartment fill specifications typically define much lower dew points (manufacturer dependent).

Measurement of Water Vapor in Sulphur Hexafluoride, SF 6. Authors: Bob Hardy, RH Systems, Albuquerque, NM, USA Daniel Mutter, MBW Calibration, Wettingen, Switzerland. Sulphur hexafluoride, SF 6, is a non-toxic, inert, insulating and cooling gas of high dielectric strength and thermal stability. Due to its high dielectric strength, it is particularly suited for application in high power circuit breakers as well as in high-voltage cables, transformers, and switchgears.
