The authors evaluate, in this paper, the interruption capability of gas mixtures by simulating the decay of a nonblown wall-stabilized arc at atmospheric pressure. They have calculated, by a one-dimensional (1-D) transient model assuming local thermodynamic equilibrium and solving the mass and energy conservation equations, the variations of temperature and conductance. From the calculations, they can bring out that the most efficient gas for the interruption capability is the SF{sub 6}, and that the mixtures SF{sub 6}-CF{sub 4} and SF{sub 6}-C{sub 2}F{sub 6} are more efficient than SF{sub 6}-N{sub 2} mixtures.
