Every IEEE Standard is subjected to review at least every ve years for revi-sion or reafrm

When a document is more than ve years old and has not been reafrmed, it is reasonable to concludethat its contents, although still of some value, do not wholly reect the present state of the art.

When the ne

For this reason, IEEE and the members of its soci-eties and Standards Coordinating Committees are not able to provide an instant response to interpretation requests except inthose cases where the matter has previously received formal consideration.

23、roduction is not part of IEEE Std C57.12.80-2002, IEEE Standard Terminology for Power and DistributionTransformers.)This revision of ANSI/IEEE C57.12.80 incorporates a substantial number of changes since the last majorrevision in 1978. In addition to providing many new terms, some of the more signic
24、ant changes include:a) The terms and their denitions are now listed in alphabetical order.b) Cross-references are made to certain terms that appear in the International Electrotechnical Com-mission Multilingual Dictionary of Electricity, Electronics and Telecommunications. These termscan be identied
25、 when “(IEC)” follows the term.c) Numerous cross-references have been added to related terms in the standard. These appear follow-ing the denition and are denoted by See also, Syn, See, andContrast.d) Obsolete cooling class designations (OA, OA/FA, etc.) have been so designated and the correspond-in
26、g new terms (ONAN, ONAN/ONAF, etc.) have been added.e) More precise denitions have replaced some previous denitions and miscellaneous correctionshave been made.ParticipantsAt the time this standard was completed, the working group on Standard Terminology for Power and Distri-bution Transformers had
