Abstract
In the expulsion type of oil circuit breaker the arc occurring on circuit interruption is ``expelled'' from the contact chamber by a high velocity gas blast. Breakers of this type have demonstrated their capability of consistently interrupting short circuits on a typical large electric power system within 1 or 2 cycles of arc. In this paper the theory of this type of breaker is presented and its performance is analyzed.Keywords
