Highly sensitive Gas Insulated Switchgear Service

May 05, 2017Abstract: Phosphorene is a promising candidate for gas sensing materials. This letter describes our study of the adsorption of sf6-gas and sf 6 decomposition gases (SO 2 and H 2 S) on phosphorene. We used first principles calculations to explore phosphorene's potential applications as gas sensor to diagnose the state of online gas insulated switchgear (GIS).
