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.

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 preliminary written test and an oral test, which constitutes the actual exam and determines the awarding of credits. Those who have obtained a positive evaluation in the written test are admitted to the oral test. Passing the test is subject to the correct numerical resolution of the questions, and the correct formulation of the solution to the problem is generally a necessary but not sufficient condition. The written test consists of the numerical solution of one or two exercises, in a time limit of 90 minutes, in which technical questions are asked relating to the topics covered by the course, such as: the solution of electrical circuits in steady state in alternating current, single-phase or three-phase, the determination of the operating conditions of electrical machines under specified load conditions, the calculation of the operating conditions of electrical distribution systems.
