Major revisions have been made in this edition to coordinate with the revisions to ANSI/IEEE C37.04, ANSI C37.06, ANSI/IEEE C37.09, and ANSI/IEEE C37.20.2 in 1999-2000. The historic

33、 voltage range factor (K) has been changed to a value of 1.0, effectively eliminating the voltage range factor from the standards. This simplifies testing of products, and test procedures from ANSI/IEEE C37.09 have been incorporated where appropriate. Since both the voltage range factor (K) and asym

34、metry factor (S) have been eliminated, the “Required asymmetrical interrupting capability (It)” described in clause 5.8.2.2 of ANSI/IEEE C37.04 has been used to define the service capability demonstration in Test Duty SC2. This formerly was a value of 400% KSI and the new value of 400% Itis equivale

35、nt. Explanatory text has been added to clause 4.3.1 relative to trip-free requirements, as ANSI/IEEE C37.04 does not include the historic trip-free adjective in discussing the mechanism requirements in clause 6.9(1) of that document. This language has been added to avoid future confusion for users o

36、f this document. Since this edition eliminates the voltage range factor, circuit breakers with K 1.0 which may be produced after the approval date of this standard should have conformance tests conducted in accordance with the procedures in the 1996 edition of C37.54. This standard has been revised

37、by the Power Switchgear Assemblies Technical Committee of the Switchgear Section, the National Electrical Manufacturers Association (NEMA 8SGV). This standard was developed to describe selected tests and procedures to demonstrate conformance in accordance with clause 6.2 ANSI/IEEE C37.09. The scope

38、of this standard is limited to Conformance Test Procedures for Indoor Alternating Current High-Voltage Circuit Breakers Applied as Removable Elements in Metal Enclosed Switchgear Assemblies. To facilitate its use and to permit timely revisions based on experience, a separate document has been provid

39、ed. This standard is one of several in a series of test procedure standards for conformance testing of switchgear products. While this standard is written for general guidance, performance criteria are established so that this standard can be adopted as the basis for certification of identified circ

40、uit breakers for use in installations subject to regulation by public authorities and similar agencies concerned with law ordinances, regulations, administrative orders and similar instruments. It is noted that certain utility installations continue to be excluded from the scope of this standard as

41、a result of historic discussions among representatives from EEI and NEMA. Suggestions for improvements are welcome, and should be sent to the National Electrical Manufacturers Association, 1300 North 17thStreet, Rosslyn, VA 22209. This standard was processed and approved for submittal to ANSI by Acc

42、redited Standards Committee on Power Switchgear C37. Committee approval of the standard does not necessarily imply that all committee members voted for its approval. At the time of its approval, the C37 Committee had the following members: T. Olsen, Chair J. Collins, Secretary vi ANSI C37.54-2002 (R

47、 Current High-Voltage Circuit Breakers Applied as Removable Elements in Metal-Enclosed Switchgear Conformance Test Procedures 1 General 1.1 Scope 1.1.1 Scope and objectives When conformance tests are required, this standard specifies tests to demonstrate that the circuit breaker being tested conform

48、s with the ratings assigned to it in accordance with ANSI/IEEE C37.04. Preferred ratings are listed in ANSI C37.06. As a requirement of conformance testing, the circuit breaker shall have completed the design testing requirements of ANSI/IEEE C37.09. If ANSI/IEEE C37.09 tests have not been previousl

49、y performed, the tests required by ANSI/IEEE C37.09 beyond tests described by this standard may be performed concurrently with conformance testing. NOTEAdditional tests per ANSI/IEEE C37.09 need not be witnessed by the certifying party. 1.1.2 Application This standard applies to Indoor Alternating Current High-Voltage Circuit Breakers rated above 1000 volts used as removable elements in Metal-Enclosed Switchgear Assemblies in accordance with clause 3.1.5 “Metal-Clad Switchgear” of ANSI/IEEE C37.20.2. 1.
