Understanding IEC 60726 Dry-Type Power Transformers: A Comprehensive Guide
A single amendment was issued for the 1982 edition: . The amendment is a short document of only 2 pages and is available in English and French. As with the main standard, the amendment has now been replaced and is no longer current, but it is nevertheless part of the full historical record. Today, the amendment can be purchased from national IEC member bodies, typically for a modest fee (e.g. CHF 10 from the IEC webstore or €11 from the Belgian CEB‑BEC).
This loading guide has also been superseded and replaced by (Power transformers - Part 12: Loading guide for dry-type power transformers), which now aligns with IEC 60076-11.
