GOALI: Under-Load Evaluation of Breaker Contacts Condition

9634600 El-Sharkawi 断路器是电力系统中最关键的元件之一。公共和公用事业人员的安全以及系统运行的可靠性取决于断路器的性能。 因此，断路器需要进行严格的维护。 不幸的是，如果有可靠和经济的方法用于断路器触点状态的有载评估，则会产生大量费用，而这些费用本来可以避免。本提案介绍了这样做的一个项目。 我们对成功的期望是基于另一个项目的出色结果，该项目是华盛顿大学、SCE、NSF和EPRI之间的合作：汽轮发电机转子绕组中的短匝检测器。 此外，该项目将为电力工业和学术界之间的技术信息和专门知识的重要交流提供一个独特的机会。 ***

9634600 El-Sharkawi The circuit breaker is one of the most critical elements in a power system. The safety of the public and utility personnel, and the reliability of the system operation depends on the breaker's performance. Circuit breakers are therefore subjected to rigorous maintenance. Unfortunately, a large expense is incurred that could otherwise be avoided if a reliable and economic method for on-load evaluation of breaker contacts conditions was available. A project to do so is described in this proposal. Our expectations of success are predicted on the excellent results in another project-collaboration between the University of Washington, SCE, the NSF and EPRI: The Shorted-Turn Detector in Turbo-Generator Rotor Windings. In addition, this project will provide an unique opportunity for an important exchange of technical information and expertise between the electric utility industry and academia. ***
