Organization: IEEE
Publication Date: 11 September 2009
Status: active
Page Count: 127
scope:

Concepts of power bus protection are discussed in this guide. Consideration is given to availability and location of breakers, current transformers (CTs), and disconnectors, as well as bus-switching 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 (BF) protection is discussed as pertaining to bus protection. Means of securing bus protection schemes against corrupted relay input signals are also included.

Purpose

The purpose of the guide is to assist utility engineers and industrial and commercial plant engineers in selecting and engineering proper bus protection.
