Technical information is provided in this guide related to liquid-immersed power, distribution, and regulating transformers that are designed to operate at temperatures that exceed the normal thermal limits of IEEE Std C57.12.00(TM), under continuous load, in the designed average ambient and at rated conditions. Guidelines for applying high-temperature solid and liquid materials as insulation systems; guidelines for loading high-temperature liquid-immersed power, distribution, and regulating transformers; and guidelines on test procedures for qualifying new high-temperature solid and liquid insulating materials are included.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
P1276a
Guide for the Application of High-Temperature Insulation Materials in Liquid-Immersed Distribution, Power, and Regulating Transformers Amendment: Updates to Annex B and corresponding references in Annex D
The amendment is adding updated and new insulation system aging examples and other additional related information to Annex B, and corresponding references in Annex D.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
1276-1997
IEEE Guide for the Application of High-Temperature Insulation Materials in Liquid-Immersed Power Transformers
Technical information is provided related to liquid-immersed power transformers insulated with high-temperature materials.Guidelines for applying existing qualified high- temperature materials to certain insulation systems,recommendations for loading high- temperature liquid-immersed power transformers,and technical information on insulation-system temperature ratings and test procedures for qualifying new high-temperature materials are included.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
