Abstract
THE successful interruption of large currents at high voltages has been the subject of considerable research, the general aim being to bring about a low-energy release in the circuit breaker by having a short arcing period. During recent years, attention has been focused on the use of a high-velocity blast of gas to effect consistently rapid interruption and at the same time avoid setting up destructive voltage surges in the circuit. Numerous oscillograms have shown that final interruption takes place towards the end of a half-cycle, and for this reason great interest has been taken in the de-ionizing influences which are active immediately after current zero.
