  • 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.
