High-Voltage Circuit Breakers in the Bonneville Power System [includes discussion]

This paper discusses the purposes of a large number of circuit breaker tests of many domestic and foreign makes performed on the Bonneville Power System. The tests were made either for studying only the circuit breaker´s operation in interruption of short-circuit current and of line charging current, or were part of over-all system tests including energization of new lines, setting of relays, et cetera.
