IEEE C57.12.60-2020 IEEE Standard for Thermal Evaluation of Insulation Systems for Dry-Type Power and Distribution Transformers

IEEE C57.12.60-2020 Стандарт IEEE для тепловой оценки изолирующих систем сухого типа и распределения электроэнергии Трансформаторы

This test procedure for the thermal evaluation of insulation systems of dry-type power and distribution transformers is to be used for determining the temperature classification and modification of the insulation systems. This standard shall apply to all dry-type transformers with a voltage of 601 V or higher in the highest voltage winding except as follows:a) Instrument transformersb) Step- and induction-voltage regulatorsc) Arc-furnace transformersd) Rectifier transformerse) Specialty and general-purpose transformersf) Mine transformersg) Testing transformersh) Welding transformers
