-49,5 °C at 226 kPa (2.26 bar). So when measuring humidity in terms of frost/dew point in the typical SF 6 range (-3…-60 °C) using a chilled mirror hygrometer, there is clearly a risk that an optically detected condensate layer could be SF 6. From a humidity perspective this adds a potentially significant measurement uncertainty,

The Problem with Humidity in Sulfr hexafluoride Gas-Insulated Systems

Humidity in SF 6 Gas 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).

sf 6 Gas Analysis - Qrometric

For Sulfr hexafluoride filled gas compartments, sf6 gas 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).

The three parameters that determine the quality — sf6 gas concentration, humidity and quantity of decomposition products — can now be measured in one single operation with the new sf6 gas Multi-Analyser. As a result, service specialists can determine on-site whether the gas still complies with the IEC Standard 60480 or whether it needs purification.
