  • SF6 Monitoring System for GIS – GE Grid Solutions

    B Watch. SF 6 Monitoring System for GIS. With worldwide scrutiny on SF 6 gas usage, increased environmental reporting requirements and even possible penalties, precise early detection of small gas leaks in Gas Insulated Substations that use so much SF 6 is essential. The B Watch uses the latest generation of EMC resistant digital gas sensors to continuously measure gas pressure and temperatures in order to track changes in density and detect gas

    Gas monitoring is done with g3 as it was with SF6. Traditional sensors (temperature-compensated pressure switches) have only to be adapted to the updated pressure. Digital sensors for on-line monitoring do not require changes; just the software needs updating according to the physical properties of the g3 mixture. Digital

  • Gas density monitors and gas density sensors for SF6

    Trafag gas monitoring devices measure the gas density directly, i.e. SF6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF6 Gas Density Sensors, or by combining both principles, i.e.SF6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF6 gas density.
