IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus development process, approved by the
8、American National Standards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE administers the process and establishes rules to p
9、romote fairness in the consensus development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its standards. Use of an IEEE Standard is wholly voluntary. The IEEE disclaims liability for any personal injury, property or other dama
10、ge, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance upon this, or any other IEEE Standard document. The IEEE does not warrant or represent the accuracy or content of the material contained
11、 herein, and expressly disclaims any express or implied warranty, including any implied warranty of merchantability or fitness for a specific purpose, or that the use of the material contained herein is free from patent infringement. IEEE Standards documents are supplied “AS IS.” The existence of an
12、 IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about
13、 through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revision or reaffirmation. When a document is more than five years old and has not been reaffirmed, it is reasonable to conclude th

In publishing and making this document available, the IEEE is not suggesting or rendering professional
15、or other services for, or on behalf of, any person or entity. Nor is the IEEE undertaking to perform any duty owed by any other person or entity to another. Any person utilizing this, and any other IEEE Standards document, should rely upon the advice of a competent professional in determining the ex
16、ercise of reasonable care in any given circumstances. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to
17、 prepare appropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committe
18、es are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his
19、or her views should be considered the personal views of that individual rather than the formal position, explanation, or interpretation of the IEEE. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. Suggestions for changes
20、in documents should be in the form of a proposed change of text, together with appropriate supporting comments.

Introduction This introduction is not part of IEEE Std C57.93-2007, IEEE Guide for
23、 Installation and Maintenance of Liquid-Immersed Power Transformers. Power transformers usually represent one of the most important and most costly single items in substations. Furthermore, particularly for large transformers, their failure usually results in lengthy outages or downgrading of servic
24、e. For these reasons, a high degree of care is required to properly install and maintain them. Because of these considerations, IEEE and other standards-developing organizations have published, since at least the early 1920s, various recommendations for testing, installing, and maintaining transform
25、ers. This guide consolidates and replaces IEEE Std C57.12.11-1980 and IEEE Std C57.12.12-1980, which cover large transformers, and ASA C57.93-1958, which covers smaller units. The intention of this guide is to assist users and manufacturers in the shipping, handling, inspection, installation, and ma
26、intenance of liquid-immersed power transformers and to assure that the units are placed in service in acceptable condition to provide years of reliable service. This guide also provides information on developing a maintenance and monitoring program. NOTEThe manufacturer may specify more stringent re
27、quirements than this guide. For transformer warranty validation and other reasons, the manufacturers guidelines should be followed. This guide discusses the following two sizes of transformers: 501 kVA to 10 MVA, or with primary windings less than 69 kV 10 MVA and above, or with high-voltage winding
28、s of 69 kV and above The working group of this guide recognizes that substantial variations exist among transformer manufacturers on certain aspects of transformer installation requirements and that these vary with size and voltage. This guide attempts to accommodate these variations and facilitate
29、a full understanding between manufacturer and user. Generally, the user must conform to the manufacturers minimum recommendations in order to obtain a proper warranty. Notice to users Laws and regulations Users of these documents should consult all applicable laws and regulations. Compliance with th
30、e provisions of this standard does not imply compliance to any applicable regulatory requirements. Implementers of the standard are responsible for observing or referring to the applicable regulatory requirements. IEEE does not, by the publication of its standards, intend to urge action that is not
31、in compliance with applicable laws, and these documents may not be construed as doing so. Copyrights This document is copyrighted by the IEEE.
