Power transformers - Part 15: Gas-filled power transformers

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".
