    The scope of this work covers the effective gas capture, re-use and sealing techniques of gaz sf6 gas in a HV GIS circuit breaker. National Grid loses in the region of 12,000kg of Sulfr hexafluoride every year, due to the sheer amount of insulating gas switchgear there is installed on the Transmission system. This equates to nearly 30% of National Grids UK carbon emmissions.
