Comments on standards Comments 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 advic

16、e pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a 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 ques

17、tions also receive the concurrence of a balance of interests. For this reason, IEEE and the members of its 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 th

18、e same reason, IEEE does not respond to interpretation requests. Any person who would like to participate in revisions to an IEEE standard is welcome to join the relevant IEEE working group.

25、hese documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance of amendments, corrigenda, or errata. An official IEEE document at any point in time consists of the current edition of the document together with any amendments, cor

When a document is more than ten years old and 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

27、 state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE standard.

Patents Attention is called to the possibility that implementation of this standard may require use of subject matter covered by patent rights. By publication of

30、this standard, no position is taken by the IEEE with respect to the existence or validity of any patent rights in connection therewith. If a patent holder or patent applicant has filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE-SA Website a

Letters of Assurance may indicate whether the Submitter is willing or unwilling to grant licenses under patent rights without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfa

The IEEE is not responsible for identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal

The Accredited Standards Committee on Transformers, Regu

44、lators, and Reactors, C57, has for many years has been developing standards on transformers, regulators, and reactors. The data has been obtained from many sources, including the standards of the Institute of Electrical and Electronics Engineers, Inc. (IEEE) and the National Electrical Manufacturers

45、 Association (NEMA), as well as reports of committees of the Edison Electrical Institute, manufacturers, end users, and others. The revision of this standard includes additional mechanical and electrical requirements for accessories relating to pressure relief, loadbreak switch, and overcurrent prot

46、ection. The revision makes changes, including but not limited, to the following topics: Tank material Impedance voltage changes Kilovolt-ampere rating The revision also addresses various corrections and omissions not previously captured in the 2009 revision.
