Extinction of A-C. arcs in turbulent gases

IN CIRCUIT breakers employing arcs submerged in liquids such as oil, carbon tetrachloride, or water, the surrounding liquid surface serves both to restrict the are space and to furnish a gas blast by rapid decomposition under the influence of the high temperature arc. The fiber tube of the common expulsion fuse acts in a similar manner. In the liquid circuit breakers, various devices are available to increase the interaction between arc and liquid, thus aiding in arc extinction.
