TR 1-201X Page iii 2014 National Electrical Manufacturers Association FOREWORD This foreword is not part of NEMA TR1-2013 Transformers, Step Voltage Reg
13、ulators, and Reactors. The standards appearing in this publication have been developed by the Transformer Section and have been approved for publication by the National Electrical Manufacturers Association. They are used by the electrical industry to promote production economies and to assist users
14、in the proper selection of transformers. The Transformer Section is working actively with the IEEE Committee, C57 on Transformers, Regulators, and Reactors, in the development, correlation, and maintenance of national standards for transformers. This Committee operates under the procedures both the
15、American National Standards Institute (ANSI) and the Institute of Electrical and Electronics Engineers (IEEE). It is the policy of the NEMA Transformer Section to remove material from the NEMA standards publication as it is adopted and published in the IEEE C57 series standards. The NEMA standards p
16、ublication for Transformers, Regulators, and Reactors references these and other American National Standards applying to transformers, and is intended to supplement without duplication both the American National and IEEE standards. The NEMA standards publication for Transformers, Regulators and Reac
17、tors contains provision for the following: a. IEEE and American National Standards adopted by reference and applicable exceptions approved by NEMA if any. b. NEMA Official Standards ProposalsThese are official drafts of proposed standards developed within NEMA or in cooperation with other interested
18、 organizations, for consideration by ANSI and IEEE. They have a maximum life of ten years, during which time they must be revised as American National Standards, IEEE standards, or adopted as NEMA standards, or rescinded. c. Manufacturing StandardsThese are NEMA standards which are primarily of inte
19、rest to the manufacturers of transformers and which are not yet included in an American National or IEEE standards. d. Standards Which Are ControversialThese are NEMA standards, on which there is a difference of opinion within Committee C57. The NEMA version will be included in the NEMA standards pu
20、blication until such time as the differences between ANSI, IEEE, and NEMA are resolved. NEMA standards publications are subject to periodic review and take into consideration user input. They are being revised constantly to meet changing economic conditions and technical progress. Users should secur
21、e latest editions. Proposed or recommended revisions should be submitted to: Senior Technical Director, Operations National Electrical Manufacturers Association 1700 13th Street, Suite 900 Rosslyn, VA 22209 TR 1-2013 Page iv 2014 National Electrical Manufacturers Association This standards publicati

35、e factory in accordance with the conditions outlined in IEEE Std. C57.12.90-2010. The guaranteed sound levels should continue to be per Tables 1 through 2 until such time as enough data on measured noise power levels becomes available. Sound pressure levels are established and published in this docu
36、ment. Sound power may be calculated from sound pressure using the method described in C57.12.90-2010. Rectifier, railway, furnace, grounding, mobile and mobile unit substation transformers are not covered by the tables. The tables do not apply during operation “of” on load tap changers in power tran
