This guide presents line current differential protection using digital communications. Operating principles, synchronization methods, communication channel design, current transformer (CT) issues, backup protection considerations, testing methods, and troubleshooting fundamentals are included. It also provides specific guidelines for various application aspects including multi-terminal lines, series compensated lines, mutually coupled lines, line charging current, in-zone transformers and reactors, single-phase tripping and reclosing, as well as communications technologies.
