• Moisture Measurement Control in Sulfr hexafluoride Gas Switchgear

    What is the dew point of an gaz sf6 system having a moisture content of 300 PPMV at guage pressure 152 kPa (22psig) Pressure = 300 * 10 -4 (22 + 14.7) 51.7 = 0.57mmHg The 51.7 multiplier is used to convert the pressure from psia to mmHg for use with Table :1 (760 mmHg = 14.7 psi, so 1 psi = 760/14.7 = 51.7 mmHg)

  • The Problem with Humidity in gaz sf6 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.
