5、: This guide sets forth recommendations believed essential for the application of overcur- rent protective devices that limit the exposure time of dry-type transformers to short-circuit currents. This guide is not intended to imply overload capability. Keywords: dry-type transformers, normal base cu
6、rrent, overcurrent protective devices, transform- er short-circuit impedance 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 dev
7、elop- ment process, approved by the American National Standards 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 with- out compensation. While the IEEE administers
8、 the process and establishes rules to promote fairness in the consensus devel- opment 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 an
9、y personal injury, property or other dam- age, 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 ac
10、curacy or content of the material contained herein, and expressly disclaims any express or implied warranty, including any implied warranty of merchantability or fi tness for a specifi c purpose, or that the use of the material contained herein is free from patent infringement. IEEE Standards docume
11、nts are supplied “ AS IS .” The existence of an 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 approve
12、d 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 least every fi ve years for revi- sion or reaffi rmation. When a document is more than fi ve years old and has
13、not been reaffi rmed, it is reasonable to conclude that its contents, 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,
14、 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 entity to another. Any person utilizing this, and any other IEEE Standards document, should rely upon the ad
15、vice of a com- petent professional in determining the exercise of reasonable care in any given circumstances. Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specifi c applications. When the need for interpretations is brought to the
16、 attention of IEEE, the Institute will initiate action to 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 mem
17、bers of its soci- eties and Standards Coordinating Committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration. Comments for revision of IEEE Standards are welcome from any interested party, reg
18、ardless of membership affi liation 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 standards and requests for interpretations should be addressed to: Secretary, IEEE-SA Standards Board 445

23、ion is not a part of IEEE Std C57.12.59-2001, IEEE Guide for Dry-Type Transformer Through-Fault Current Duration.) This guide provides recommendations for the application of overcurrent protection devices to limit the expo- sure time of dry-type transformers to short circuits. It must not be confuse
24、d with IEEE Std C57.109 -1993, IEEE Guide for Liquid-Immersed Transformer Through-Fault Current Duration, which applies only to liq- uid-immersed transformers. Dry-type transformers differ signifi cantly from liquid-immersed types in several respects: a) There are fi ve different temperature ratings
