Measuring Dew Point and Moisture in insulating 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 Sulfr hexafluoride equipment is -50…-20 °C. Pure Sulfr hexafluoride may be even drier.
