High-voltage oil circuit breakers
Electrical Engineering, 1950ONLY a few years ago, 3,500,000 kva was the maximum standard rated interrupting capacity for high-voltage circuit breakers, and the interrupting-time ratings were mostly five and eight cycles. This article describes recent developments in interrupting devices that have made available standard circuit breakers for 5,000,000-kva interrupting capacity and

Timings of high voltage circuit-breaker
Electric Power Systems Research, 2008The reliability of an electrical power system is influenced by the operation of circuit-breaker (CB). A good indicator of circuit-breaker condition is its switching time. Based on it some of the critical circuit-breaker irregularities can be detected and removed before they develop to a failure.

Transactions of the American Institute of Electrical Engineers, 1923
The 150-kv. system operated for some years by the Southern California Edison Company has not made use of automatic operation of circuit breakers. The multiplication of generating stations and connections which accompanied the change to 220-kv. makes desirable the automatic sectionalizing of the line in cases of trouble and, therefore, requires circuit ...

Acoustic diagnosis of high voltage circuit-breakers
IEEE Transactions on Power Delivery, 1992A noninvasive technique for assessing the condition of circuit breakers by considering the acoustic signals generated during nonenergized switching is described. Mechanical malfunction, wear, and other types of abnormal behavior can be detected as changes in this acoustic signature.
