This guide covers general recommendations for the loading of dry-type distribution and power transformers that have 80°C, 115°C, and 150°C average winding rises, and insulation systems limited to 150°C, 185°C, and 220°C maximum hottest-spot operating temperatures, respectively. Transformers through 10 000 kVA are included. Recommendations for ventilated, nonventilated, and sealed dry-type transformers having impregnated insulation systems are provided.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
PC57.96
IEEE Draft Guide for Loading Dry-Type Distribution and Power Transformers
General recommendations for the loading of dry-type distribution and power transformers installed in ventilated, non-ventilated, and sealed type enclosures are included in this standard.
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.
C57.96-1999
IEEE Guide for Loading Dry-Type Distribution and Power Transformers
Reaffirmed 2004. General recommendations for the loading of dry-type distribution and power transformers that have 80 °C, 115 °C, and 150 °C average winding rises and insulation systems limited to 150 °C, 180 °C, and 220 °C maximum hottest-spot operating temperatures, respectively, are covered in this guide. Recommendations for ventilated, nonventilated, and sealed dry-type transformers having impregnated insulation systems 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No Inactive-Withdrawn Standards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.
C57.96-2013
IEEE Guide for Loading Dry-Type Distribution and Power Transformers
General recommendations for the loading of dry-type distribution and power transformers installed in ventilated, non-ventilated, and sealed type enclosures are included in this standard.
