Operation, Maintenance, and Field Test Procedures for Protective Relays and Associated Circuits. Facilities Instructions, Standards, and Techniques Volume 3-8

摘要

The Bureau of Reclamation (Reclamation) operates and maintains 58 hydroelectric powerplants and many switchyards, pumping plants, and associated facilities that are important to electric power and water delivery systems. These facilities house complex electrical and mechanical equipment; and protective relays and associated circuits play an essential role in protecting this equipment as well as the electric power system. This document defines Reclamation practices for operating, maintaining, and testing protective relays and protection circuits. The Western Electricity Coordinating Council, North American Electric Reliability Council, National Fire Protection Association, and Reclamation practices are the basis of these practices. Included in this document are standards, practices, procedures, and advice on day-to-day operation, maintenance, and testing of existing relaying systems, which also includes periodically verifying relay settings furnished by others.
