Objectifs Généraux
1. The students will be able to acquire a solid knowledge of the technical vocabulary and main characteristics of components used in the three-phase systems. 2. Determine how an electrical network operates, from the power production to the distribution of the power to the low voltage network. 3. The students will be able to apply the frequency domain analysis to a three-phase system. 4. Analyse the power management of a three-phase system and explain how to compensate the reactive power in a three-phase system. 5. The students will be able to determine a realistic model of a single-phase transformer and evaluate the power calculations of single-phase transformers.
