Full Description

Scope

This standard applies to all types of electrically controlled ac high-voltage circuit breakers rated above 1000 V. This standard applies for any type of power-operated mechanism and for both ac and dc control power. Only the basic control elements of the circuit breaker, including reclosing where required, are included in this standard. This standard does not include devices or circuits for protective relaying, special interlocking, etc., since these are dependent upon the specific application of a particular circuit breaker

Purpose

The purpose of this standard is to establish basic requirements for ac high-voltage power circuit breaker control schemes so that users and manufacturers can effect engineering and production economies by reducing the multiplicity of special control schemes that are specified in the absence of standards.

Abstract

Revision Standard - Superseded.Standard requirements for all types of electrical control circuits for ac high-voltage breakers rated above 1000 V are given. This standard is applicable for any type of power-operated mechanism and for both ac and dc control power. Only basic control elements of the circuit breaker, including reclosing where required, are included in this standard. Devices or circuits for protective relaying, special interlocking, etc., are not included.
