Circuit Breaker Testing Standards

This part of ISO 10924 defines terms and specifies general test requirements for circuit breakers for use in road vehicles with a nominal voltage of 12 V d.c., 24 V d.c, 48 V d.c. and 450 V d.c. This part of ISO 10924 is intended to be used in conjunction with other parts of...

Scope and objectives When conformance tests are required, this Standard specifies tests to demonstrate that the circuit breaker being tested conforms with the ratings assigned to it in accordance with ANSI/IEEE C37.04. Preferred ratings are listed in ANSI C37.06....

This test code summarizes the various tests which may be made on power circuit breakers and describes accepted methods used in making these tests. These tests may be divided into two classifications: (a) Design Tests (b) Production Tests...

This guide is intended to provide a basis for synthetic testing of circuit breakers (see ANSI/IEEEC37.04-1979 [2]) and to establish the criteria for testing to demonstrate the short-circuit current rating of circuit breakers on a single phase basis....

This technical report is applicable to class E2 circuit-breakers rated 72,5 kV and above, intended for use on overhead lines.

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 Short-Circuit...

PURPOSE AND SCOPE This document summarises the results of short-circuit testing of re-furbished OBR60 and OBR60/72E circuit-breakers and makes recommendations regarding the continued use of these designs on the National Grid electricity transmission system. The...

This SAE Standard defines the test conditions, procedures, and performance requirements for circuit breakers in ratings up to and including 200 A. The document includes automatic reset, modified reset, and manually reset types of circuit breakers for 12 VDC, 24...

This document provides a recommended practice for the selection, application, and determination of the remaining life in molded-case circuit breakers used in industrial applications. Purpose Molded-case circuit breakers are one of the most widely used circuit...

The purpose of this procedure, is to provide a model process for the checks and tests to be performed on a circuit breaker fail scheme which is being extended (as a result of adding a new Feeder Bay), at an existing double busbar substation with individual relay rooms. The...

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...

This guide provides a basis for synthetic capacitive current switching tests (see IEEE Std C37.04-1999) and to establish guidelines for testing to demonstrate the capacitive switching rating of circuit breakers on a single phase basis. The guide contains typical...

Gives design information and specifies test methods for aircraft circuit breakers.

PURPOSE The purpose of this procedure, is to provide a model process for the checks and tests to be performed on a circuit breaker fail scheme which is being extended (as a result of adding a new Feeder Bay), at an existing double busbar substation with a common relay room. The...

Scope and object This part of IEC 60947 series applies to circuit-breakers, intended to be installed and operated by instructed or skilled persons, the main contacts of which are intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1...

Scope and object This part of IEC 60947 series applies to circuit-breakers, the main contacts of which are intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.; it also contains additional requirements for integrally...

00489a-000000-000000 1 Scope 1.1 The requirements of this standard cover single pole or multi-pole DC rated circuit breakers intended for use as branch circuit overcurrent and short-circuit protection in communications equipment. 1.2 All poles of multi-pole...

This part of IEC 62271 is applicable to a.c. circuit-breakers designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V It is only applicable to three-pole circuit-breakers for use in...
