PC57.100 - Standard Test Procedure for the Thermal Evaluation of Insulation Systems for Liquid-Immersed Distribution, Power and Regulating Transformers
This standard applies to the insulation systems used in all liquid-immersed distribution, power and regulating transformers. This standard provides test procedures to evaluate the thermal aging characteristics of insulation systems used in liquid-immersed distribution, power or regulating transformers. The dielectric liquid is part of the insulation system.
IEEE 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.
IEEE 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.
