CF3I Gas Mixtures: Breakdown Characteristics and Potential for Electrical Insulation

SF6 is a potent greenhouse gas, and there has been research into more environmental friendly alternative gases with the aim of replacing the use of SF6 gas in high-voltage equipment. So far, the research into alternative gases has shown that CF3 I gas mixtures have promising dielectric properties comparable to those of SF6 . This paper provides an overview of research into CF3 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.
