  • A Solid State Gas Density Monitor for Gas Insulated

    Abstract: A solid state gas density monitor has been developed for SF6 service in gas-insulated substation equipment that is based on principles and construction techniques similar to ionization-type fire alarms. The monitor has a resolution of .7kPa (.1 psi) at 20&C. and, depending on ion chamber voltage and geometry, exhibits a linearity of ±1. to ±4. kPa (±.15 to ±.6 psi) at 20&C. over the density

  • sf6-gas Gas Mixture monitor for Substation

    Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and other characteristic component gases.
