– 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:

– 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”.
