Abstract
THE RAPIDLY INCREASING demand for circuit breakers with extremely high interrupting capacities has resulted in the development of the 10,000-megavoltampere (mva) 138-kv 3-cycle oil circuit breaker which is described. The short-circuit current requirements of the new rating surpass those previously encountered at the higher transmission voltages including the 10,000-mva rating at both 161 and 230 kv. However, these and all other specifications have been met successfully with the breaker illustrated in Fig. 1.
