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.
