13、 Official statements A statement, written or oral, that is not processed in accordance with the IEEE-SA Standards Board Operations Manual shall not be considered or inferred to be the official position of IEEE or any of its committees and shall not be considered to be, or be relied upon as, a formal

14、 position of IEEE. At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be considered the personal views of that individual rather than the formal position of IEEE. Comments on standards Comme

15、nts for revision of IEEE Standards documents are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not provide consulting information or advice pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a

16、proposed change of text, together with appropriate supporting comments. Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comments and questions also receive the concurrence of a balance of interests. For this reason, IEEE and the members of its

17、 societies and Standards Coordinating Committees are not able to provide an instant response to comments or questions except in those cases where the matter has previously been addressed. For the same reason, IEEE does not respond to interpretation requests. Any person who would like to participate

18、in revisions to an IEEE standard is welcome to join the relevant IEEE working group. Comments on standards should be submitted to the following address: Secretary, IEEE-SA Standards Board 445 Hoes Lane Piscataway, NJ 08854 USA Laws and regulations Users of IEEE Standards documents should consult all

Updating of IEEE Standards documents Users of IEEE Standards documents should be aware that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance of amendments,

25、corrigenda, or errata. An official IEEE document at any point in time consists of the current edition of the document together with any amendments, corrigenda, or errata then in effect. Every IEEE standard is subjected to review at least every ten years. When a document is more than ten years old an

26、d has not undergone a revision process, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE standard. In order to determine whether a

27、given document is the current edition and whether it has been amended through the issuance of amendments, corrigenda, or errata, visit the IEEE-SA Website at http:/ieeexplore.ieee.org/xpl/standards.jsp or contact IEEE at the address listed previously.

This latest re

43、vision to the IEEE Std 638 is a revision of IEEE Std 638-1992 and is the result of a review of IEEE Std 638-1992 and present practices in Class 1E transformer qualification. This revision incorporates current practices and lessons learned from the implementation of previous versions of this standard

44、 by the industry. IEEE Std 638 was developed to provide specific methods and test procedures for the qualification of Class 1E transformers in accordance with IEEE Std 323, which provides guidance for demonstrating and documenting the qualification of electrical equipment used in all Class 1E and in

45、terface systems. This latest revision has clarified or updated a number of items, including removing references to old IEEE standards that are no longer in use today, incorporating the information from the 7 April 1999 Correction to IEEE 638-1992 into the body of the document, and updating certain a

46、spects of the document to be more in line with the latest versions of the related transformer standards referenced in this document. Additionally, the modern technique of frequency response analysis (FRA) was incorporated into the qualification tests to be performed as part of this standard. Perform

47、ing the FRA tests before and after the short-circuit test and seismic test will provide better insight into the actual condition of the transformer after completion of these two significant tests, further improving the understanding of the tested transformer designs capability to withstand such even

48、ts in operation. Adherence to this document alone may not suffice for assuring public health and safety because it is the integrated performance of the structures, fluid systems, instrumentation systems, and electrical systems of the nuclear power generating station that establish safe operating con

49、ditions. This standard was prepared by Working Group P638 of the Power Transformers Subcommittee of the Transformers Committee of the IEEE Power and Energy Society. Copyright 2014 IEEE.
