  • Byproducts of Sulfur Hexafluoride (SF6) Use in the

    electrical discharge decomposition products and impurities (as well as the presence of SF 6 itself) makes measurement of the different byproducts problematic. A recent report in Transmission and Distribution World summarized methods that may allow for on-site and field monitoring of SF 6 byproducts with portable instrumentation (Baumbach et al. 2000).
