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 high-voltage 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.
