12、IONAL STANDARD Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, sub

13、stantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution.

14、 The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American

15、 National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Stand

16、ards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. Caution Notice: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute r

17、equire that action be taken periodically to reaffirm, revise, or withdraw this standard.

40、This standard is a conformance testing standard optionally applicable to all metal-enclosed interrupter switchgear assemblies designed, tested, and manufactured in accordance with ANSI/IEEE C37.20.3. The requirement of ANSI/IEEE C37.20.3 is sufficient for application of metal-enclosed interrupter sw

41、itchgear assemblies, and conformance testing is not necessary to satisfy the basic requirements of that standard. Conformance testing is performed to show compliance with the basic requirements when required to satisfy special agreements or regulatory agency requirements. Conformance testing may be

42、performed associated with the basic design testing if agreeable to those concerned; however, conformance testing is more likely to be performed some time after original development to satisfy a special need. Conformance testing need not be performed if not required. Metal-enclosed interrupter (MEI)

43、switchgear may include control and instrumentation components unique for the application, which are not individually evaluated under this standard. NOTEIn this standard, the use of the term “MEI switchgear“ shall be considered to mean “metal-enclosed interrupter switchgear.“ This standard does not c

45、ch purposes or located outdoors on property owned or leased by the utility or on public highways, streets, or roads, or outdoors by established rights on private property. NOTEAn electric utility is an entity that is overseen by a public utility commission, a public service commission, or other regu

46、latory agency having jurisdiction for such installations. 1.1 General This standard specifies the tests that shall be required to demonstrate that the MEI switchgear being tested conforms with the ratings assigned to it and meets the electrical and mechanical performance requirements specified in AN

47、SI/IEEE C37.20.3. 1.2 Definitions 1.2.1 Design tests Design tests are tests made by the manufacturer to determine the adequacy of the design of a particular type, style, or model of equipment or its component parts to meet its assigned ratings and to operate satisfactorily under normal service condi

48、tions or under special conditions if specified. Design tests may be used to demonstrate compliance with applicable standards of the industry. 1 ANSI C37.57-2003 (R2010) NOTES (1) Design tests are made on representative apparatus or prototypes to verify the validity of design analysis and calculation

49、 methods and to substantiate the ratings assigned to all other apparatus of basically the same design. These tests are not intended to be made on every design or to be used as part of normal production. The applicable portion of these design tests may also be used to evaluate modifications of a previous design and to assure that performance has not been adversely affected. These data from previous similar designs may also be used for current designs, where appropriate. Once made, the tests need not be repeated unless the design is changed so as
