This reference guide lists common IEEE device numbers and corresponding protection and control functions used in electric power systems, providing a quick reference for relay identification and application.
The life expectancy of digital excitation systems is influenced by the availability of spare and replacement parts. Many factors affect the ability of manufacturers to continue producing these systems and providing replacement parts. Strategies exist for prolonging the life of existing digital equipment and minimizing the cost impact of complete replacement.
This product bulletin provides an overview of the features, benefits, specifications, and configuration options of the AVC Sensing Module.
This drawing provides panel cutout, drilling, and mounting dimensions for installation of the DECS-150 Digital Excitation Control System.
This Spanish-language application note explains how the DECS-2100 excitation control system uses bridge paralleling and redundancy configurations to increase field current capacity, improve reliability, and maintain operation during rectifier bridge failures or maintenance activities.
This application note describes how the BE1-50/51B Self-Powered Overcurrent Retrofit Relay with Hot Line Tag (HLT) improves worker safety during maintenance and switching operations. It explains HLT functionality and highlights retrofit benefits that help reduce arc-flash hazards and simplify replacement of legacy electromechanical relays.
This application note outlines upgrades to DECS-2100 accessory modules, replacing aging electronic components with updated designs to improve reliability, maintainability, and long-term availability while maintaining compatibility with existing excitation system installations.
This application note explains dead bus synchronization using the DECS-150 Digital Excitation Control System. It describes how multiple generators can be started, synchronized, and connected together before excitation is applied, simplifying black start and emergency power applications.
