• SF 6 is a potent greenhouse gas, and there has been research into more environmental friendly alternative gases with the aim of replacing the use of SF 6 gas in high-voltage equipment. So far, the research into alternative gases has shown that CF 3 I gas mixtures have promising dielectric properties comparable to those of SF 6 . This paper provides an overview of research into CF 3 I gas and its mixtures, and gives an insight into its key properties. These include laboratory tests on the gas mixtures and initial applications to electrical power equipment. The insulation capability makes CF 3 I a feasible alternative to SF 6 as an insulation medium where arc quenching is not required. On the other hand, iodine deposition after electrical discharge means CF 3 I may not be a suitable arc quenching gas for switchgear applications that require high current interruption unless a solution is found for controlled capture of the iodine.
