Highly sensitive sf6 Alternatives re-use in Ghana

Cited by: 25Author: Ruyue Cui, Lei Dong, Hongpeng Wu, Shangzhi Li, Lei Zhang, Weiguang Ma, Wangbao Yin, Liantuan Xiao, S...Publish Year: 2018IntroductionLine SelectionSensor DesignConclusionsSulfur hexafluoride (SF6) has been widely used as an insulating medium in electric power transmission equipment of a 110 kV high-voltage power grid, such as gas-insulated switchgear (GIS) and gas circuit breakers (GCBs). The monitoring of the operating condition of electric power transmission equipment is vital to ensure failure-free operation of the electric power transmission lines. The online detection for SF6 decomposition is an effective means for fault early warning of electric power transmission equipment, which is based on the fact that SF6 can be decomposed in the case of superheating and a partial discharge (PD) caused by latent inner insulation defects. In this process, various sulfur-containing, fluorine-containing compounds, such as SF4, HF, SO2F2, SOF2, SO2, CO2,CO, SF4, are generated via a reaction between water, oxygen, metal vapor or other impurities [1–5]. These decomposition gases can be employed as indicator gases to locate and identify fault types and their loc...See more on osapublishing.org(PDF) Highly sensitive gas leak detector based on a quartz researchgate.net/publication/304894937_Highly...Article [50] describes a highly sensitive SF 6 PA leak detector with a threshold sensitivity of ~2.7 ppb, which is based on QCL (λ = 10.56 μm, ~ 25 mW) and a resonant PA detector in the form of
