Objectives
Au terme du cours, l'étudiant-e doit être capable de :
- Reconnaître les lois fondamentales régissant le fonctionnement des machines à courant alternatif.
- Poser les équations en régime permanent, définir et justifier le modèle de chaque machine (les transformateurs mono- et triphasés).
- Utiliser les modèles pour la résolution de problèmes, analyser et défendre les résultats obtenu
-
Content
Introduction aux différentes machines et leurs modèles (MAS, MS et Transfo)
Transformateurs monophasés et triphasés

- Facteurs de distribution, de raccourcissement du pas, d'enroulement
- Détermination de la tension induite
Type of teaching and workload
Course specification
Evaluation methods
- Continuous assessment Written work, Practical exercises / Evaluated reports
Course grade calculation method
The mark for the continuous assessment is the weighted average of the mark for the written exams and the grade for the practical work -- The weighting coefficients are communicated to the students at the beginning of the course or activities that are being assessed. In the case of a revision exam, the final mark for the course is the arithmetic average of the mark for the continuous assessment and the mark for the revision exam. Attendance is mandatory. In the case of more than 20% absence from class, the teacher will not give a grade to the student and without valid justification, the course will be considered as failed. Cases of force majeure are reserved.
