Partial Discharge and Breakdown Characteristics in N2/O2 and N2/CO2 Gas Mixtures Under Inhomogeneous Electric Field
Since SF6 gas was specified to be a greenhouse gas at COP3 in 1997 because of its high global warming potential (GWP=23900), the development of new insulating gases or gas mixtures alternative to SF6 gas is greatly needed. Especially, gas mixtures without the use of SF6 gas will be expected as the ultimate substitutes to SF6 gas.
