This guide describes methodologies for determination of the steady-state winding hottest-spot temperature in dry-type distribution and power transformers. This guide applies to all dry-type transformers, including those with ventilated, sealed, solid cast, and encapsulated windings except transformers described as exceptions in IEEE Std C57.12.01.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
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.
C57.134-2000
IEEE Guide for Determination of Hottest-Spot Temperature in Dry-Type Transformers
Methodologies for determination of the steady-state winding hottest-spot temperature in dry-type distribution and power transformers with ventilated, sealed, solid cast, and encapsulated windings built in accordance with IEEE Std C57.12.01-1998 and IEC 60726 (1982-01) are de-scribed in this guide. Converter transformers are not included in this guide.
C57.134-2013
IEEE Guide for Determination of Hottest-Spot Temperature in Dry-Type Transformers
Methodologies for determination of the steady-state winding hottest-spot temperature in dry-type distribution and power transformers with ventilated, sealed, solid cast, and encapsulated windings built in accordance with IEEE Std C57.12.01(TM) and IEC 60726 are described in this guide. Converter transformers are not included in this guide.
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No Inactive-Withdrawn Standards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
