    Abstract - (Show below) - (Hide below)

    IEC 60076-15:2015 applies to three-phase and single-phase gas-filled power transformers (including auto-transformers) with the exception of certain categories of small and special transformers such as:
    - single-phase transformers with rated power less than 1 kVA and three-phase transformers less than 5 kVA;
    - transformers, which have no windings with rated voltage higher than 1 000 V;
    - instrument transformers;
    - traction transformers mounted on rolling stock;
    - starting transformers;
    - testing transformers;
    - welding transformers. This second edition of IEC 60076-15 cancels and replaces the first edition published in 2008 and constitutes a technical revision. The following main technical changes from the first edition are:
    - Modified in accordance with the related revised standards of IEC 60076-1, IEC 60076-2, IEC 60076-3 and related items of SF6 gas in the revised standard of "High-voltage switchgear and controlgear;
    - Added the clause "minimum power under alternative cooling modes";
    - Added the clause "safety, environmental and other requirements";
    - Added the clause "d.c. currents in neutral circuits";
    - Added the clause "electromagnetic compatibility (EMC)";
    - Added the clause "high frequency switching transients".
