In this paper, we present the results of a comparative study of breakdown voltage of CO2, N2 and SF6 gases, and CO2-SF6 and N2-SF6 mixtures under different types of voltage namely AC, DC and lightning impulse voltage in a sphere-to-sphere electrodes arrangement. The equivalencies between breakdown voltage of SF6 and those of mixtures with respect to pressure and percentage of SF6 in CO2 and N2 are presented and discussed.
