SF6-alternatives Density Monitors GE

Environmental friendly alternatives of products by GE, the green transformer and the g3 insulated switchgear were the key items on display in GE's booth. Siemens had the Blue GIS switchgear on display, which uses clean air as the insulation medium as their environment friendly alternative to the traditional SF6 insulated range.

  • SF6 Monitoring System for GIS – GE Grid Solutions

    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

  • Gas density monitors and gas density sensors for SF6 and

    Trafag gas monitoring devices measure the gas density directly, i.e. SF 6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF 6 Gas Density Sensors, or by combining both principles, i.e.SF 6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF 6 gas density.
