IEEE Std 242-1986. IEEE Recommended Practice for Protection and Coordination of Industrial and Commercial Power Systems (The IEEE Buff Book);

ANSI/IEEE Std 242-1986, the IEEE Buff Book, has been extensively revised and updated since it was first published in 1975. The Buff Book deals with the proper selection, application, and coordination of the components which constitute system protection for industrial plants and commercial buildings. System protection and coordination serve to minimize damage to a system and its components in order to limit the extent and duration of any service interruption occuring on any portion of the system. A valuable, comprehensive sourcebook for use at the system design stage as well as in modifying existing operations, the IEEE Buff Book is arranged in a convenient step-by-step format. It presents complete information on protection and coordination principles designed to protect industrial and commercial power systems against any abnormalities which could reasonably be expected to occur in the course of system operation.
