Rotating electrical machines - Part 2-2: Specific methods for determining separate losses of large machines from tests - Supplement to IEC 60034-2-1
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 60034‑2‑1. 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.
Drehende elektrische Maschinen - Teil 2-2: Besondere Verfahren zur Bestimmung der Einzelverluste großer elektrischer Maschinen aus Prüfungen - Ergänzung zu IEC 60034-2-1
Machines électriques tournantes - Partie 2-2: Méthodes spécifiques pour déterminer les pertes séparées des machines de grande taille à partir d'essais - Complément à l'IEC 60034-2-1
L'IEC 60034-2-2:2024 s'applique aux machines électriques tournantes de grande taille et établit des méthodes supplémentaires pour la détermination des pertes séparées et qui sont destinées à définir un rendement, en complément de l'IEC 60034‑2‑1. Ces méthodes s'appliquent lorsqu'un essai à pleine charge n'est pas possible ou qu'il présente une plus grande incertitude. Les méthodes spécifiques décrites sont: - la méthode de la machine étalonnée; - la méthode du ralentissement; - la méthode calorimétrique; - la sommation des pertes pour les machines synchrones avec une excitation à aimants permanents. Cette deuxième édition annule et remplace la première édition parue en 2010. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) alignement de la disposition et des procédures sur l'IEC 60034-2-1 et l'IEC 60034-2-3; b) ajout de l'Annexe A: procédure informative pour la sommation des pertes des machines synchrones de grande taille avec une excitation à aimants permanents.
