IEC 60034-2-2:2024 applies to large rotating electrical machines and establishes additional methods of determining separate losses and to define an efficiency supplementing IEC 60034\u20112\u20111. These methods apply when full-load testing is not practical and results in a greater uncertainty. The specific methods described are: – Calibrated-machine method. – Retardation method. – Calorimetric method. – Summation of losses for permanent magnet excited synchronous machines. This second edition cancels and replaces the first edition published in 2010. This edition includes the following significant technical changes with respect to the previous edition: – Layout and procedures aligned with IEC 60034-2-1 and IEC 60034-2-3. – Annex A added: an informative procedure for the summation of losses for large permanent-magnet excited synchronous machines.<\/p>\n
