    Abstract - (Show below) - (Hide below)

    IEC 60076-14:2013 applies to liquid-immersed power transformers employing either high-temperature insulation or combinations of high-temperature and conventional insulation, operating at temperatures above conventional limits. It is applicable to:
    - power transformers in accordance with IEC 60076-1;
    - convertor transformers according to IEC 61378 series;
    - transformers for wind turbine applications in accordance with IEC 60076-16;
    - arc furnace transformers;
    - reactors in accordance with IEC 60076-6. This part of IEC 60076 may be applicable as a reference for the use of high-temperature insulation materials in other types of transformers and reactors. This first edition of IEC 60076-14 cancels and replaces the second edition of the Technical Specification IEC/TS 60076-14 published in 2009. It constitutes a technical revision.
