  • Highly selective detection of sulfur hexafluoride

    Aug 01, 2018 · SF 6 has been widely used in gas-insulated switchgear (GIS) because of its excellent properties in insulating and arc-extinguishing . However, partial discharges (PDs) will occur with the existence of inevitable intrinsic defects in GIS, causing SF 6 decomposes into SO 2 , SOF 2 , SO 2 F 2 , and H 2 S under the reaction with trace water and oxygen [ 2 , 3 ].
