Abstract :
The Power Systems Reliability Subcommittee strives to maintain current reliability data on major electrical equipment to assist the industry in accomplishing realistic and meaningful reliability studies. This paper presents the results of a low-voltage circuit breaker reliability survey achieved through the use of available results from testing during preventive maintenance. A substantial number of test results were obtained to allow credible results for a few different circuit breaker categories. A similar set of results was published by Kornblit (1990). Most of these results have been incorporated into this new expanded effort
