The course provides basic principles of Electrical Engineering and Electro-mechanics. These concepts are then applied to the study of fundamental and advanced electrical machines (motors and generators), and to the analysis of energy transmission and distribution systems. An introduction to future electrical smart grids is also presented.

The course is based on lectures in classroom wherein theoretical concepts are taught, and on exercises in classroom with the goal of directly applying the techniques for design and analysis of electrical power systems which are described during the lectures.
Each scheduled exam includes a written examination composed of exercises and theoretical questions, followed by a short oral examination concerning the whole programme of the course. The conventional evaluation procedure can be substituted by intermediate tests covering the three main topics that compose the programme.
The first part of the programme includes a brief review of some basic concepts of electrical circuit theory that are widely used during the course.
