Consideration is given to availability and location of breakers, current transformers, and disconnectors as well as busswitching scenarios, and their impact on the selection and application of bus protection. A number of bus protection schemes are presented; their adequacy, complexity, strengths, and limitations with respect to a variety of bus arrangements are discussed; specific application guidelines are provided. Breaker failure protection is discussed as pertaining to bus protection. Means of securing bus protection schemes against corrupted relay input signals are also included. Keywords: breaker-and-a-half, breaker failure (BF) protection, breaker substitution, buses, check zone, CT saturation, current transformers, differential bus protection, double-bus double-breaker, double-bus single-breaker, dynamic bus replica, electric power substations, high-impedance differential, main bus, partial differential, percentage differential, protective relaying, ring bus, single-bus single-breaker, stub bus, transfer bus, voltage trip supervision, zone-interlocked bus protection.IEEE Std.IEEE Std C37.234-2009: IEEE Guide for Protective Relay Applications to Power System BusesIEEE Unapproved Draft Std PC37.234/D9.10, Jun 2009IEEE Std C37.234-2009Protective relaysProtective relays.621.317NjHacINjHaclDOCUMENT996281047103316IEEE guide for protective relay applications to power system buses2580213UNISA01122nam0 22002891i 450 UON0028976020231205103916.48507-13-16367-420070313d1982 |0itac50 baengGB|||| 1||||ˆThe ‰Classical Age of German Literature 1740-1815Victor LangeLondonEdward Arnold1982275 p.22 cm.CLASSICISMOGermaniaUONC061995FILetteratura tedescaStoriaSec. 18.UONC061988FIGBLondonUONL003044830.09Letteratura tedesca.
