Abstract
We evaluate, in this paper, the interruption capability of gas mixtures by simulating the decay of a nonblown wall-stabilized arc at atmospheric pressure. We 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 our calculations, we can bring out that the most efficient gas for the interruption capability is the SF6, and that the mixtures SF6-CF4 and SF6-C2F6 are more efficient than SF6-N2 mixtures
