  • SF6 Monitoring System for GIS – GE Grid Solutions

    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 leaks down to 0.1% per year.

    The key difference between g3 and SF6 is that g3 is a gas mixture while SF6 is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process. To ensure this homogeneity, the filling
