New types of SF6 intermupting chambers that implement innovative interrupting principles have been developed during the past years based on the objectives of reducing the operating energy of the circuit breakers and consequently increasing their reliability. This paper describes the rear-exhaust type self-blast double-volume thermal chamber, which was designed with the help of new chamber development software programs, of the physical imaging model of the arc. Simulations and confirmation by laboratories tests interruption of short circuit currents and especially tests short circuit currents having a nonpassage by zero on such new chamber for applications to generator circuit breakers are shown and evaluated.
