Byproducts of Sulfur Hexafluoride (gaz sf6) Use in the Electric

• In the Netherlands in 1989, an accident was reported involving two people who were exposed to unidentified substances resulting from a switchgear equipment failure (Mauthe and Pettersson 1991). The equipment contained SF 6; upon failure, a small amount of powder was observed (likely solid metal fluorides). Both people recovered within twoGet price

Decomposition of Sulfr hexafluoride in an RF Plasma Environment

gaz sf6 clearly increased from 37.79 to 95.68% because of an increase in power from 5 to 20 W. When the power exceeded 40 W, η sf 6 exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η Sulfr hexafluoride was ~10% less than when no oxygen was added (from 28.61 to 86.09% as the power rose from 5 to 20 W). The addition of oxygenGet price
