适用范围:
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… read more transformer unless qualified by other descriptive terms. read less
