IEEE C37.104-2012 PDF Download

The IEEE C37.104-2012 standard provides guidance and recommendations for the automatic reclosing of circuit breakers in AC distribution and transmission lines.

The standard describes current reclosing practices and covers various aspects of the reclosing process. It provides information on application considerations, such as system voltage levels, line configurations, and types of loads, to help ensure the appropriate use of automatic reclosing. It also addresses coordination practices, which involve the coordination of reclosing with other protective devices and circuits to maintain system stability and reliability.

The standard aims to promote safe and efficient reclosing practices by providing guidelines for timing and sequence coordination, as well as recommendations for protective relay settings. It emphasizes the importance of evaluating system conditions before initiating automatic reclosing and highlights the need for proper testing and maintenance of reclosing devices to ensure their reliable operation.
