Gas Insulated Switchgear Decomposition Quantitative

The Siemens range of gas-insulated switchgear (GIS), for rated voltages from 72.5 kV up to 550 kV, is an extremely successful product concept. Since its introduction back in 1968, Siemens has installed switch fields in all climatic zones of the earth, recording over 420,000 years of operation since.

  • The SF6 Decomposition Mechanism: Background and

    Abstract Gas 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.Cited by: 1
