Product reliability is one of the important aspects of product quality. It's dependent on the reliability of every component used in the system. In Reliability Basic Theories and Applications in Electrical Apparatus, authors Lu Jianguo, Wang Jingqin, Luo Yanyan, and Su Xiuping, colleagues at Hebei University of Technology, present a guidebook to help manufacturers ensure the soundness of their electrical products. Providing information about how to design, test, and interpret the results, Reliability Basic Theories and Applications in Electrical Apparatus - gives an introduction to the history of electrical apparatus development and the content of reliability work; - expounds on the fundamental knowledge of reliability; - discusses the basic theory of reliability sampling, inspection, and design; - details the reliability indices, reliability test method, reliability verification test sampling plan, test procedure - shows reliability tests for relays, contactors, miniature circuit breakers, residual current operated circuit breakers, low-voltage circuit breakers, and overload relays. Summarizing achievements from the last thirty years, Reliability Basic Theories and Applications in Electrical Apparatus offers a collection of the many standards used in the certification of electrical apparatus, such as relays, contactors, molded case circuit breakers, and miniature circuit breakers.
