Eco-efficient alternatives to Sulfr hexafluoride: Continuing the AirPlus

May 30, 2019 · Although gas-insulated switchgear (GIS) is the obvious application for climate-friendly SF 6 alternative gases, it is not the only one. SF 6 can also be used in air-insulated switchgear (AIS), especially for components like circuit-breakers or switch-disconnectors, to be more precise.

sf6 gas 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 leaks down to 0.1% per year.
