Because of environmental priorities defined by international agreements such as the Kyoto Protocol and Doha Amendment, the restrictions on the use of SF6 make these studies an obligation. Although the number of alternative dielectric gases studied for this purpose is quite high, these gases can be classified under the titles of non-synthetics, hydrocarbons (HCs), fluorocarbons (FCs), hydrofluorocarbons (HFCs), fluoronitriles (FNs), fluoroketones (FKs) and other synthetic gases. In this study, the gases classified under these titles are compared using the dielectric constant relative to SF6, Global Warming Potential (GWP), atmospheric lifetime, boiling point and toxicity parameters used in the comparison of dielectric gases. When compared with these parameters, non-synthetic air, CO2, and N2, C3F7CN from FNs, and C5F10O and C6F12O from FKs stand out among alternative gases to SF6. These alternatives are used in some innovative power system industry applications and have a widespread use potential in the insulating gas industry instead of SF6.}, number={3}, publisher={Tayfun UYGUNOĞLU}
