Learning aims
Learning outcomes Study programme competences
The student will identify the various phenomena (reactive, imbalances and harmonics) that can be found in an electrical system or installation, which reduce its efficiency, will know how to quantify their importance and proceed to propose the best solution for them, so that the system is as efficient as possible from the electrical point of view, in accordance with current standards and regulations.

Methodologies
Methodologies Description
Workshop The student will be provided with the necessary teaching material to be able to develop the contents of the subject.
Supervised projects Methodology designed to promote students' autonomous learning, under the tutelage of the teacher and in varied settings (academic and professional). It refers primarily to learning "how to do things." It constitutes an option based on the assumption by students of responsibility for their own learning.
This teaching system is based on two basic elements: the independent learning of the students and the monitoring of that learning by the teacher-tutor.
Objective test Evaluation test where the student must demonstrate their level of learning in an objective manner.
