Windings temperature and loss of life of an induction machine under voltage unbalance combined with over- or undervoltages / Gnacinski, P. in IEEE transactions on energy conversion, Vol. 23 n°2 (Juin 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°2 (Juin 2008) . - pp. 363 - 371 Titre : Windings temperature and loss of life of an induction machine under voltage unbalance combined with over- or undervoltages Type de document : texte imprimé Auteurs : Gnacinski, P., Auteur Année de publication : 2008 Article en page(s) : pp. 363 - 371 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  machines;  machine  windings;  overvoltage Résumé : This paper deals with the effect of simultaneous voltage unbalance and over- or undervoltage on windings temperature and thermal loss of life of an induction cage machine. The presented results of investigations are based on the experiment and thermal modeling. The influence of an angle of the complex voltage unbalance factor (CVUF) on machine heating is considered. The effect of synergy of voltage unbalance and voltage rms value deviation is presented. Two induction machines of different properties are compared. One of them has a comparatively weakly saturated magnetic circuit, and the other a comparatively strongly saturated circuit. The former is especially exposed to overheating in the conditions of undervoltage, and the latter in the conditions of overvoltage.
