sf6 gas Decomposition in Gas-Insulated Equipment - IEEE Journals

In the presence-of an electric arc, spark or corona, sf 6 decomposes to a wide variety of chemically active products which possess completely different properties from sf 6. The accumulation of these decomposition products in the equipment has caused concerns regarding personnel safety and material compatibility problems. This paper reviews previous research in sf 6 decomposition relating to the operation of gas-insulated switchgears, gas-insulated transmission lines, and electrostaticGet price
