The effective application of relays for protection of power system electrical buses is addressed. Common bus arrangements and some special arrangements used in the United States are covered; not all bus protection systems or all possible bus arrangements are included. Factors that determine the need and type of bus protection, and basic principles of bus protection operation are discussed. Relay input sources are covered. Bus protection systems and common bus arrangements with relay input sources are described. Also discussed are current transformer locations, wiring and grounding, location of the bus on the system, bus construction, problems associated with switching and bypassing, auxiliary tripping relays, reclosing of breakers after a bus differential operation, testing of bus differential relaying, and bus backup protection.

No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
