Since 1926 many significant field tests on high-voltage circuit breakers have been made on the American Gas and Electric Company's central system, which have served as an important aid in highvoltage circuit breaker development. Such tests have also served as a means for studying and checking the behavior of this large power system under short-circuit conditions. A 138-kv air-blast breaker of novel...
A description of a new multibreak interrupter for fast clearing of short circuits applicable to high-voltage conventional tank-type oil circuit breakers. Breakers equipped with such interrupters were subjected to interrupting tests on large 138-kv and 230-kv systems during which short circuits as high as 2,000,000 kva were interrupted in less than five cycles. The results of those interrupting tests...
