In the event that an IEEE standard is translated, only the English version published by IEEE should be considered the approved IEEE standard. Official Statements A statement, writt

Comments on Standards Comments for revision of IEEE Standards docu
16、ments 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 proposed change of text, together with
17、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 societies and Standards Coordinating C
18、ommittees 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 in revisions to an IEEE standard is wel

Updating of IEEE Standards Documents Users of IEEE Standards documents should be aware that these documents may be superseded at any time by the issuance of new editions or may be amended from time to time through the issuance of amendment
21、s, 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
22、 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 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
23、 a 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.

By publication of this standard, no position is taken by the IEEE with respect to the existence or validity of any patent rights in connection
26、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 at http:/standards.ieee.org/about/sasb/patcom/patents.html. Letters of Assurance may indicate whether the Submitter is willing
27、 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 unfair discrimination to applicants desiring to obtain such licenses. Essential Patent Claims may exist for which a Letter of Ass
28、urance has not been received. The IEEE is not responsible for identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or scope of Patents Claims, or determining whether any licensing terms or conditions provided in connection with sub
29、mission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non-discriminatory. Users of this standard are expressly advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility. Furt

All rights reserved. vii Introduction This introduction is not part of IEEE Std C57.12.01-2015, IEEE Standard for General Requirements for Dry-Type Distribution and Power Transformers. This standard is the result of an effort
41、 encompassing the interests of users, manufacturers, and others dedicated to producing voluntary consensus standards for dry-type transformers. This standard was first published in 1979, and was revised and updated in 1989, 1998, and 2005. In the current version of the standard, the title has been r
42、evised to reflect the standards inclusion of all types of dry-type transformers, without specific reference to newer types. In addition, the dielectric insulation table has been expanded to include 46.0 kV and 69.0 kV system voltages, and the references have been updated. Further, informative Annex
43、A, Bibliography, and informative Annex B, Insulation at high altitude, have been added, and the standard has again been updated to match current style guide requirements. Moreover, as part of ongoing efforts, the clause on partial discharge testing was revised to improve harmonization of this standa
44、rd with international standards such as IEC 60076-11. This revision included removing the table on partial discharge limits and pre-stress limits, and replacing it with discussion and a figure describing the IEC partial discharge testing methodology. The dielectric tests discussed in this standard c
45、onsist of low-frequency and high-frequency testing. Low-frequency tests include induced voltages up to two times rated volts, which are intended to verify the integrity of turn-to-turn and layer-to-layer insulation systems. Applied potential tests verify the integrity of major insulation systems to
46、ground and between separate windings. High-frequency tests include a 1.2 50 s wave and a chopped wave to verify the integrity of electrical windings to withstand lightning and switching transients. It is important to reference NEMA ST-20aand the National Electrical Code (NEC) (NFPA 70)b, cas these s
47、tandards refer to this standard. NEMA ST-20 is a standard for dry-type transformers with primary windings connected to secondary distribution circuits with voltages of 600 V and below usually installed and used in accordance with the National Electric Code. NEMA ST-20 is referenced in this introduct
48、ion for information on voltages 600 V and below applications only. This revision was developed by the Working Group of the Dry-Type Transformers Subcommittee of the IEEE Transformers Committee of the IEEE Power and Energy Society. This standard is a voluntary consensus standard. Its use may become m
49、andatory only when required by a duly constituted legal authority, or when specified in a contractual relationship. To meet specialized needs and to allow innovation, specified changes are permissible when mutually determined by the user and the producer, provided such changes do not violate existing laws and are considered technically adequate for the function intended. aNEMA publications are available from Global Engineering Documents, 15 Inverness Way East, Englewood, CO 80112, USA (http:/ bNFPA publications are available from Publications Sales,
