The heavy expansion brought about on the Central System of the American Gas and Electric Company in response to demands for power during the defense and war periods has produced a requirement for circuit-breaker rupturing duties close to 3,500 megavolt-amperes. In order to test the interrupting performance and reliability of two types of 138-kv 3,500-megavolt-ampere circuit breakers, the first an oil, the second an air-blast design, and also to explore faster reclosing cycles than now offered… CONTINUE READING
