insulating gas Gas Analysis - Qrometric

For sf 6 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).
