Programme

Review of electromagnetism fundamentals, basic principles and theorems for the analysis of electric and magnetic circuits. Representation of sinusoidal electric quantities, definition of circuit impedance and analysis of single-phase and three-phase circuits; instantaneous power, active power and power factor in single-phase and three-phase circuits.
Instruments and methods for measuring current, voltage, active power, power factor and energy in single-phase and three-phase circuits.
Basic principle and operating characteristics of power transformers.
Theory of the rotating magnetic field; basic structure and operating characteristics of induction and synchronous machines.
Components and systems being used in power plants devoted to either generation or transportation or distribution of the electric energy; protection against either overvoltages or overcurrents; sizing of low-voltage secondary-network systems; power-factor correction; protective grounding and safety-related aspects in power distribution systems.

Prerequisiti

It is assumed that the basic knowledge of Mathematical Analysis, with particular reference to the concepts of derivative and integral, as well as the use of complex numbers and the knowledge necessary for solving first-order differential equations with constant coefficients. In addition, it is assumed that basic knowledge of Physics is known and sufficiently matured, particularly those related to the concepts of force, work, and energy, as well as the fundamental aspects of electromagnetism that are covered in high school and in the first year of undergraduate engineering degree programs. The first part of the course briefly summarizes the concepts and laws underlying the applications of electromagnetism in engineering.

Type of delivery of the course

Lectures with discussion of theoretical and applied aspects related to the topics of the teaching program.

Attendance

Class attendance is not mandatory but strongly recommended to benefit from continuous interaction with both the lecturer and other students.

Type of evaluation

The exam consists of a first practical written test and a second written test, to which only those who have passed the first test are admitted. Passing the first test depends on the correct numerical solution of the problems; the correct formulation of the solution alone is generally a necessary but not sufficient condition. The first written exam consists of solving one or two numerical problems within a 90-minute time limit. These problems involve technical questions related to the topics covered in the course, such as: solving electrical circuits in steady-state alternating current (AC) conditions, whether single-phase or three-phase; determining the operating conditions of electrical machines under specified load conditions; and calculating the operating conditions of electrical distribution systems. The second written exam, which includes at least two theoretical questions related to the topics covered in the course, constitutes the actual exam and determines the awarding of course credits.
