gis substation leak rate abb

MEPPI had a reputation for very low sf6-gas 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.
