C57.12.60-1992 - IEEE Trial-Use Standard Test Procedures for Thermal Evaluation of Insulation Systems for Solid-Cast and Resin-Encapsulated Power and Distribution Transformers
Standard Details
A uniform method is established for determining the temperature classification of solidcast and resin-encapsulated power and distribution transformer insulation systems by testing rather than by chemical composition. These insulation systems are intended for use in transformers covered by IEEE Std C57.12.01-1989 and IEEE Std C57.12.91-1995 as they apply to solidcast and resin-encapsulated transformers whose highest voltages exceed nominal 600 V.
