What's New in C37.113 - IEEE Guide for Protective Relay Applications to Tranmission Lines
This paper provides a summary of the changes that were made to IEEE Standard C37.113 - 1999. Guide for Protective Relay Applications to Transmission Lines. Topics include the selection of communication systems, redundancy, auto reclosing, ground overcurrent, line length and source impedance ratio considerations. Further, it also covers line terminated into transformers, current differential applications, ground path configurations, effects of high grounding resistance, transfer bus and stub bus configurations, scheme polarization methods, specially shaped characteristics, single phase tripping and reclosing.
