Dear Mr. Prevost:

I am pleased to inform you that on 14 June 2001 the IEEE-SA Standards Board approved the above referenced projects until December 2005. Copies of the files are attached in .pdf format.

Now that your projects have been approved, please forward a roster of participants involved in the development of these projects. This request is in accordance with the IEEE-SA Operations Manual, Clause 5.1.2f under Duties of the Sponsor which states:

\"Submit annually to the IEEE Standards Department an electronic roster of individuals

participating on standards projects\"

Attached is an Excel spreadsheet for your convenience. Please forward these lists to me via e-mail at j.haasz@ieee.org no later than 1 September 2001.

At the bottom of this e-mail, please find URLs which you may find useful in the development of your

proposed standard and in submitting your final draft for approval. We strongly recommend that a copy of your draft be sent to this office for review prior to the final voting by the working group to allow for a quick review by the editorial staff before sponsor balloting.

If you should have any further questions or would like to receive this information in paper, please contact me at 732-562-6367 or by email at j.haasz@ieee.org.Sincerely,

Jodi Haasz

Senior Administrator

Expected Date of Submission for Initial Sponsor Ballot:10/31/20018. Fill in Projected Completion Date for Submittal to RevCom:6/30/02

9. Scope of Proposed Project:

This standard is a basis for the establishment of performance, limited electrical and mechanical

interchangeability, and safety requirements of equipment described. It is also a basis for assistance inthe proper selection of such equipment. This standard describes electrical, mechanical and safety

requirements of liquid-immersed distribution and power transformers, auto transformers, and regulatingtransformers, single phase and polyphase, with voltage of 601V and higher in the highest winding.

This standard applies to all liquid-immersed distribution,power, and regulating transformers that do notbelong to the following types of apparatus:(1) Instrument Transformers

(2) Step voltage and induction voltage regulators(3) Arc Furnace Transformers(4) Rectifier transformers(5) Specialty transformers(6) Grounding transformers(7) Mobile transformers(8) Mine transformers

This standard is being revised to include technical changes to the document, which have been proposed byvarious technical working groups and sub-committees within the PES Transformers Committee. As this standarddescribes the standard general requirements for liquid immersed distribution, power and regulatingtransformers it is the intention of the working group to keep it as up-to-date as possible.

10. Purpose of Proposed Project:

This standard is a basis for the establishment of performance, limited electrical and mechanical

interchangeability, and safety requirements of equipment described. It is also a basis for assistance inthe proper selection of such equipment. This standard is being revised to include technical changes to thedocument, which have been proposed by various technical working groups and sub-committees within the PESTransformers Committee.

11. Intellectual Property

Has the sponsor reviewed the IEEE Patent policy with the Group?Yes

Are you aware of the possibility of any copyrights relevant to this project?NoAre you aware of the possibility of any trademarks relevant to this project?No

Are you aware of possible registration of objects or numbers due to this project?No

12. Are you aware of other standards or projects with a similar scope?Yes

IEC 76 - Both ANSI/IEEE Standards C57.12.00 and C57.12.90 are complementary to one another and are roughlyequivalent in scope to the IEC 76 series of publications (IEC 76-1 to 76-5). However these two sets ofstandards are not that interchangeable. Reason:

(1) The two ANSI/IEEE standards apply to liquid-immersed power transformers with the exception of (8)transformer classes. The IES 76 publications apply also to non-liquid-immersed power transformers withexceptions that are not the same.

(2) The requirements and tests that are specified by IEC 76 are often very different from those requiredby ANSI/IEEE C57.12.00.

(3) The family of ANSI/IEEE C57 standards is comprised of about 100 standards that reference oneanother. The IEC family of transformer standards is comprised of around twenty standards that are alsointerrelated. However references between both families of standards are scarce. Therefore, we have twoseparate groups of standards which have evolved more or less independently from each other and possess

different structures. In general the IEC transformers standards structure rests on the 76 standards and theC57 structure rests on C57.12.00 and C57.12.90.

13. Will this standard (in part or in whole) be submitted to an international organization for consideration/Adoption?If yes, please answer the following question:

Which International Organization/Committee?International Contact Information:

No

14. Is this project intended to focus on health, safety environmental issues?No
