IEEE C57.100-2011

IEEE Standard Test Procedure for Thermal Evaluation of Insulation Systems for Liquid-Immersed Distribution and Power Transformers

A test procedure to provide a uniform method for investigating the effect of operating temperature on the life expectancy of liquid-immersed transformers is provided. The test procedures are intended to provide data for the selection of a limiting hottest-spot temperature for rating purposes, provide data which may serve as the basis for a guide for loading, and permit the comparative evaluation of a proposed insulation system with reference to a system that has proven to be acceptable in service.

C57.100-2022

IEEE Standard for Test Procedure for Thermal Evaluation of Insulation Systems for Liquid-Immersed Distribution, Power, and Regulating Transformers

A series of test procedures to provide uniform methods for investigating the effects of operating temperature on the life expectancy of liquid-immersed transformers or insulation systems is provided. The test procedures are intended to provide data for the selection of a limiting hottest-spot temperature for rating purposes, provide data which may serve as the basis for a guide for loading, and permit the comparative evaluation of a proposed insulation system with reference to a system that has proven to be acceptable in service.

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.


C57.100-1986

IEEE Standard Test Procedure for Thermal Evaluation of Oil-Immersed Distribution Transformers

The object of this test procedure is to establish a uniform method for investigating the effect of operating temperature on the life expectancy of oil-immersed distribution transformers. It is intended to give a direct evaluation of the composite insulation system of an oil-immersed distribution transformer, tested as an integral unit. It is to be noted that the oil in which the transformer is immersed is to be considered a part of the insulation system. It is the intent of the procedure to provide that each component of the insulation structure operate during the test under conditions that are, as nearly as possible, the same as those that it would encounter in service. Thus, it is intended that each component be evaluated in accordance with its actual function.

C57.100-1999

IEEE Standard Test Procedure for Thermal Evaluation of Liquid-Immersed Distribution and Power Transformers

A test procedure is established to provide a uniform method for investigating the effect of operating temperature on the life expectancy of liquid-immersed transformers. The test proce-dures are intended to provide data for the selection of a limiting hottest-spot temperature for rating purposes, provide data which may serve as the basis for a guide for loading, and permit the com-parative evaluation of a proposed insulation system with reference to a system that has proven to be acceptable in service.
