Measuring Dew Point and Moisture in sf6 gas Gas

Most Gas Insulated Equipment (GIE) manufacturer recommend minimum and maximum tolerances for certain variables within the gas, including moisture, gas decomposition, and purity of gaz sf6. A typical dew point range for servicing the sf6 gas equipment is -50…-20 °C. Pure Sulfr hexafluoride may be even drier.
