IEEE C37.243 – IEEE Guide for Application of Digital Line Current Differential Relays Using Digital Communication

New IEEE Standard – Active.A comprehensive guide to practical line current differential schemes using digitalcommunications. Operating principles, synchronization methods, channel requirements, currenttransformer requirements, external time reference requirements, backup considerations, testingconsiderations, and troubleshooting are included. This guide also provides specific guidelines forvarious application aspects including multi-terminal lines, series compensated lines, mutuallycoupled lines, line charging current, in-zone transformers and reactors, single-phase tripping andreclosing, as well as communications channel requirements.
