Abstract
This paper evaluates the insulation performance of gas mixtures of trifluoroiodomethane and carbon dioxide (CF3I-CO2) in a medium voltage switch disconnector. Practical testing compares the results of CF3I-CO2 against SF6 to examine whether CF3I-CO2 could be a viable alternative when directly substituted into manufactured switch disconnectors in a purely insulating role. Positive standard lightning impulses were applied to the MV switchgear to determine whether CF3I-CO2 can maintain the withstand voltage for which the switch disconnector is rated when filled with SF6. The results show that certain gas mixtures of CF3I-CO2, with a higher concentration of CF3I, could be used to insulate switch disconnectors against standard lightning impulses at the rated pressure.
