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.

Foreword
The text of document 14/669/FDIS, future edition 3 of IEC 60076-2, prepared by IEC TC 14, Power
transformers, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 60076-2 on 2011-03-30.
This European Standard supersedes EN 60076-2:1997.
EN 60076-2:2011 includes the following significant technical changes with respect to EN 60076-2:1997:
— the standard is applicable only to liquid immersed transformers;
— the winding hot-spot temperature rise limit was introduced among the prescriptions;
— the modalities for the temperature rise test were improved in relation to the new thermal
requirements;
— five informative annexes were added in order to facilitate the standard application.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent

The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2011-12-30
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-03-30
Annex ZA has been added by CENELEC.
