IR SF6 sanalysis 160 Quantitative

Mar 13, 2013The concentration and types of SF 6 in Gas Insulated Switchgear (GIS) play a decisive role in the devices' insulating property. A quantitative analysis of SF 6 and its decompositions can help to find the reason of fault. In order to find the concentration information of some special ramifications of SF 6 from the infrared spectrum of GIS's gas, this paper proposes Particle Swarm ...
