No Active Projects

Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.


C57.169-2023

IEEE Guide for Determination of Maximum Winding Temperature Rise in Liquid-Immersed Transformers

Provides guidance for determining the hottest-spot temperature in distribution and power transformers built in accordance with IEEE Std C57.12.00-2000. Describes the important criteria to be evaluated by a thermal model that can accurately predict the hottest-spot temperatures in a transformer. Provides guidance for performing temperature-rise tests with direct measurement of the hottest-spot temperatures and explains the importance of developing an accurate thermal model to properly locate the temperature sensors.

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.


No Superseded Standards

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No Inactive-Withdrawn Standards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.


1538-2000

IEEE Guide for Determination of Maximum Winding Temperature Rise in Liquid-Filled Transformers

Provides guidance for determining the hottest-spot temperature in distribution and power transformers built in accordance with IEEE Std C57.12.00-2000. Describes the important criteriato be evaluated by any thermal model that can accurately predict the hottest-spot temperature in atransformer. Provides guidance for performing temperature-rise tests with direct measurement of the hottest-spot temperatures, and explains the importance of developing an accurate thermal model to properly locate the temperature sensors.
