IEEE Standard Test Procedure for Thermal Evaluation of Insulation Systems for Ventilated Dry-Type Power and Distribution Transformers
IEEE通风干式电力和配电变压器绝缘系统热评估的标准试验程序
This standard is intended to establish a uniform method for determining the temperature classification of ventilated dry-type power and distribution transformer insulation systems by test rather than by chemical composition. These insulation systems are intended for use in transformers listed in ANSI C57.12.50-1981 [1] and ANSI C57.12.51-1981 [2], and whose highest voltages exceed nominal 600 V. NOTE — In this standard, the term transformer shall be considered to mean ventilated dry-type transformer unless qualified by other descriptive terms.
