This recommended practice is intended to identify, organize and summarize information about high-voltage circuit breakers provided by the manufacturer that knowledgeable users will find useful for the receipt, installation, commissioning, operation and maintenance, and decommissioning...
This standard provides requirements for low-voltage (600 V ac and below) definite-purpose switching (LVDPS) devices (other than power circuit breakers) for use in metal-enclosed low-voltage power circuit breaker switchgear described in IEEE Std C37.20.1™.1 These...
Introduction (This introduction is not part of IEEE Std C37.081a-1997, Supplement to IEEE Guide for Synthetic Fault Testing of AC High- Voltage Circuit Breakers Rated on a Symmetrical Current Basis-8.3.2: Recovery Voltage for Terminal Faults; Asymmetrical...
This standard pertains to the requirements for direct acting current and voltage protective functions of: a) direct-acting overcurrent electromechanical trip devices b) direct-acting overcurrent electronic trip systems c) reverse-current trip systems for dc circuit breakers d)...
This guide applies to unfused low-voltage ac power circuit breakers of the 635 V maximum voltage class with separately-mounted current-limiting fuses for use on ac circuits with available short-circuit currents of 200 000 A (rms symmetrical) or less. Low-voltage ac fused...
This application guide applies to the ac indoor and outdoor high-voltage circuit breakers rated in accordance with the methods given in IEEE Std C37.04 and IEEE Std C37.04a, listed in IEEE Std C37.06™, and tested in accordance with IEEE Std C37.09 and...
Foreword This standard has been revised to include a 5000 Ampere frame size in tables 1 through 5 and tables 22A and 22B for low-voltage AC power circuit breakers. In addition, both 1000 volt and 1200 volt ratings for DC breakers in tables 11, 11a, and 12 are now included,...
This application guide covers procedures and calculations necessary to apply the standard transient recovery voltage (TRV) ratings for ac high-voltage circuit breakers with rated maximum voltage above 1000 V. The breaking capability limits of these circuit breakers are...
A Failure Reporting Form, figures 1 and 2, has been developed by the IEEE Switchgear Committee to improve the reliability of circuit breakers through uniform reporting of field failures. The use of this approach is the recommended practice for all users of power circuit...
This Standard is a conformance testing Standard optionally applicable to all metal-enclosed low-voltage ac power circuit breaker switchgear assemblies designed, tested, and manufactured in accordance with IEEE Std C37.20.1, Metal-Enclosed Low-Voltage AC Power Circuit...
This recommended practice serves as basic reference for the specification and design of field discharge circuits for synchronous machines. It also provides detailed information about field discharge equipment complementing the IEEE 421.4™-2004 Guide for Preparation of Excitation...
This test procedure summarizes the various tests that are made on ac high-voltage indoor and outdoor circuit breakers, except for generator circuit breakers, which are covered in IEEE Std C37.013-1997. It describes accepted methods used in making the tests and...
Foreword (This Foreword is not a part of ANSI/IEEE C37.18-1979, American National Standard Enclosed Field Discharge Circuit Breakers for Rotating Electric Machinery.) This standard was first published in 1962 as IEEE Publication No 90 for trial use. It was also published...
This standard provides the preferred ratings for low-voltage ac (635 V and below) power circuit breakers, fused low-voltage ac (600 V and below) power circuit breakers, general purpose dc (325 V and below) power circuit breakers, and low-voltage dc (3200 V...
Foreword (This Foreword is not a part of ANSI/IEEE C37.082-1982, IEEE Standard Methods for the Measurement of Sound Pressure Levels of AC Power Circuit Breakers.) Widespread interest in noise has prompted studies of the noise produced by power circuit...
This standard applies to all ac high-voltage generator circuit breakers rated on a symmetrical current basis that are installed between the generator and the transformer terminals. Pumped storage installations are considered a special application, and their requirements are not...
Foreword Following reports of circuit breaker failures in applications where very fast TRVs were determined to be the cause, and after thorough analysis of TRV data gathered from all parts of the world, this guide was suggested by the IEEE Switchgear Committee's Task Force on...
This recommended practice is issued as a supplement to IEEE Std C37.06 for high-voltage circuit breaker applications where the transient recovery voltage (TRV) peak is higher and/or its rise to the crest value occurs more rapidly than those specified in IEEE Std C37.06....
Foreword (This foreword is not part of ANSI C37.17-1997.) This standard supersedes and updates the 1979 edition and all previous revised editions of the original standard published in 1956, all written by the National Electrical Manufacturers Association. This standard pertains to direct-acting...
This guide describes methods to protect a power system from faults that are not cleared because of failure of a power circuit breaker to operate or interrupt when called upon by a protective relay. The intent is to give the reader a guide in how to detect that a breaker has...
