Full Description

Scope

This application guide covers procedures and calculations necessary to apply the standard transientrecovery voltage (TRV) ratings for ac high-voltage circuit breakers rated above 1000 V. The capability limits of these circuit breakers are determined to a great degree by the TRV. This application guide is not included in other existing circuit breaker standards. In this document, the TRV ratings are compared with typical system TRV duties. An example TRV calculation is given in Annex A.

Purpose

The purpose of this guide is to provide an application guide on the TRV ratings given in IEEE Std C37.041 for ac high-voltage circuit breakers rated on a symmetrical current basis. Definitions, rating structure, test procedures, and preferred transient voltage ratings and related required capabilities are included in IEEE Std C37.04, ANSI C37.06, ANSI C37.06.1, and IEEE Std C37.09. IEEE Std C37.010 applies in other respects to these circuit breakers.

Abstract

Revision Standard - Superseded.Revision of IEEE Std C37.011-1994 Procedures and calculations necessary to apply the standard transient recovery voltage (TRV) ratings for ac high-voltage circuit breakers rated above 1000 V and on a symmetrical current basis are covered. The capability limits of these circuit breakers are determined to a great degree by the TRV. TRV ratings are compared with typical system TRV duties.
