EN 60076-2:2011

Power transformers - Part 2: Temperature rise for liquid-immersed transformers

IEC 60076-2:2011 applies to liquid-immersed transformers, identifies power transformers according to their cooling methods, defines temperature rise limits and gives the methods for temperature rise tests. This new edition includes the following significant technical changes with respect to the previous edition: - the winding hot-spot temperature rise limit was introduced among the prescriptions; - the procedures for the temperature rise test were improved in relation to the new thermal requirements; - five informative annexes were added in order to facilitate the implementation of this standard.
