Important note: has been withdrawn and superseded by IEC 60076-11 (Dry-type power transformers). For current technical requirements, you should refer to IEC 60076-11 instead.
applies to dry-type power transformers with equipment voltages up to 72.5 kV. Historical Reference: IEC 60726:1982
If you design a project or specify equipment using the old IEC 60726 reference, you may be using outdated testing methodologies and environmental classifications. Modern tenders, maritime specifications, and industrial projects almost universally require compliance with the latest edition of .

If you are looking for the standard for dry-type power transformers, it is important to note that this standard has been officially withdrawn and replaced. Current Replacement: IEC 60076-11
The most critical part is the section on tests, which includes procedures for measuring winding resistance, impedance voltage, no-load loss, and various withstand and temperature rise tests, establishing a robust quality assurance framework for manufacturers.
