NDIR cf4 Analyser for gas-insulated switchgears

Mar 31, 2020 · This means that gas-insulated switchgears can be placed indoors and can be significantly smaller in size compared to air-insulated switchgears. However, it is important to monitor for low-level SF 6 leaks both due to its global warming effects but also ensuring there is no risk of damage to the switch gears, as these are normally unmanned areas.

  • A New Scheme for Residual CF4 Detection in Gas-Insulated

    Abstract: This paper presents a new scheme for the detection of residual carbon tetrafluoride (CF 4) gas in gas-insulated switchgear (GIS) for its diagnosis. For the diagnosis of GIS, the decomposition gas species including CF 4 generated by partial discharges or breakdown are analyzed. Accumulation of the gas species indicates the history of the failure of GIS.
