The IEEE develops its standards through a consensus development process, approved by the American National Standa
7、rds Institute, which brings together volunteers representing varied viewpoints and interests to achieve the fi nal product. 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
8、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 dam- age, of any nature wha

The IEEE does not warrant or represent the accuracy or content of the material contained herein, and expressl

IEEE Standards documents are supplied “ AS IS .” The existence of an IEEE Standard do
11、es 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 through developm
12、ents in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every fi ve years for revi- sion or reaffi rmation. When a document is more than fi ve years old and has not been reaffi rmed, it is reasonable to conclude that its cont
13、ents, although still of some value, do not wholly refl ect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. In publishing and making this document available, the IEEE is not suggesting or rendering professional or other s

Any person utilizing this, and any other IEEE Standards document, should rely upon the advice of a com- petent professional in determining the exercise o

When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepar
16、e 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.

23、rmer Loss Measurement.) During an earlier revision of Clause 8 and Clause 9 of IEEE Std C57.12.90, IEEE Standard Test Code for Liquid-Immersed Distribution, Power and Regulating Transformers, which describe the measurement of no load and load loss, respectively, it was realized that there was a need
24、 for a guide that would explain in more detail the accuracy requirements, test code procedures, various test methods available, methods to diagnose test anomalies, and the procedures for calibration and safety. Participants At the time this guide was completed, the working group for developing the g
