C57.12.60-2009 - IEEE Standard Test Procedure for Thermal Evaluation of Insulation Systems for Dry-Type Power and Distribution Transformers, Including Open-Wound, Solid-Cast, and Resin-Encapsulated Transformers
A uniform method is established for determining the temperature classification for the insulation systems for open-wound, solid-cast and resin-encapsulated power and distribution transformers by testing rather than by chemical composition. These insulation systems are intended for use in transformers covered by IEEE Std C57.12.01(TM) and IEEE Std C57.12.91(TM) as they apply to dry-type transformers whose highest voltages exceed nominal 600 V.

This corrigendum clarifies temperature control for aging experiments in 4.5.1 that was a result of the combination of the two previous test standards. This corrigendum selects the method from the two which should have been used in the combined test standard represented by the 2009 version. This document also makes one minor editorial change in 4.4.
