Research on Power Frequency Insulation Properties and Configurations of CF3SO2F Gas Mixture for Industrial Applications

open access: yesHigh Voltage, EarlyView.
ABSTRACT The breakdown characteristics of the novel eco‐friendly insulating gas CF3SO2F are fundamental to the design of gas‐insulated equipment. In this paper, the gas mixture parameters for CF3SO2F were optimised for different ambient temperatures in order to ascertain the insulation performance and liquefaction temperature constraints.
