recover Sf6 Gas Vacuuming Recovery And Refilling emissions

MEPPI had a reputation for very low SF 6 gas leak emissions, and it increased its stake in the project with a leak rate guarantee of less than 0.1% per unit volume per year for the GIS. An extended warranty that guarantees this leak rate for a long time provided ITC with assurance that leaks should no longer be a problem at St. Antoine.
