SF6 decomposition monitoring for middle voltages

This work is dedicated to the development of an on-line monitoring system of SF6 decomposition in electrical devices (SF6DcpMS) in order to evaluate the health condition of the devices in real time. The feature decomposition, SO2, and SF6 purity are continuously monitored. Considering the oxidation-reduction reactions of SO2

  • The SF6 Decomposition Mechanism: Background and

    2017-1-24Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and other characteristic component gases. The decompositionCited by: 1

    2016-2-11electrical discharge decomposition products and impurities (as well as the presence of SF 6 itself) makes measurement of the different byproducts problematic. A recent report in Transmission and Distribution World summarized methods that may allow for on-site and field monitoring of SF 6 byproducts with

  • OSA | Highly sensitive photoacoustic multicomponent

    A ppb-level photoacoustic multicomponent gas sensor system for sulfur hexafluoride (SF6) decomposition detection was developed by the use of two near-infrared (NIR) diode lasers and an ultraviolet (UV) solid-state laser. A telecommunication fiber amplifier module was used to boost up the excitation optical power from the twoCited by: 8
