  • Abstract
    Results are given of SF6 circuit-breaker restrike waveforms during no-load, live-line switching operations on a 362 kV network, together with laboratory tests of the early dielectric recovery of the circuit breaker. It is shown that the tendency to restrike is assisted by the excellent interrupting ability of the breaker when the initial transient recovery voltage rises at the very slow rate typical of `stiff´ networks
