On-Site SF Gas Analysis - MBW Calibration AG

-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,Get price

The Problem with Humidity in sf 6 Gas-Insulated Systems

To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS). Due to its excellent dielectric capabilities, sulfur hexafluoride (SF 6) is the preferred insulator in electrical transmission and distribution equipment. Switchgears insulated with SF 6 gas are tightly sealed. However, over the lifetime of the equipment, impurities may find their way into the gas compartment via hoses, gaskets, and gas handling equipment.Get price
