6、tees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product
7、. Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the inform
8、ation contained in its standards. Use of an IEEE Standard is wholly voluntary. The IEEE disclaims liability for any personal injury, property or other damage, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, u
9、se 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 herein, and expressly disclaims any express or implied warranty, including any implied warranty of merchantability or fitness for a spe- cific p

IEEE Standards documents are supplied “AS IS.” The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, pur- chase, market, or provide other goods and services r
11、elated 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 through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at
12、 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 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
13、that they have the latest edi- tion of any IEEE Standard. In publishing and making this document available, the IEEE is not suggesting or rendering professional 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 e
14、ntity to another. Any person utilizing this, and any other IEEE Standards document, should rely upon the advice of a competent professional in determining the exercise of reasonable care in any given circum- stances. Interpretations: Occasionally questions may arise regarding the meaning of portions
15、 of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will ini- tiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is important to ensure that any i
16、nterpretation has also received 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 interpretation requests except in those cases where the matter has previously receive
17、d formal consideration. Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affil- iation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Comments on

23、the Application of High- Temperature Insulation Materials in Liquid-Immersed Power Transformers.) Liquid-immersed transformers utilizing high-temperature insulation systems are being used increasingly by the industry, and current standards do not effectively cover their performance criteria. This gu
24、ide is intended to give the user some background information on the application and use of high-temperature insulation in power transformers. The highest allowable temperature of the transformer winding insulation is an essential parameter in determining the maximum load that a transformer may relia
