Subject fundamentals
The goal of this course is to provide the student with the basics of circuit theory and electrical applications in industrial settings. The first part of the course develops the basics of electrical circuit analysis. The second part begins with some outlines of electrical machines and transformers. Afterwards, it deals with production, transmission and distribution of electric energy, focusing then on low-voltage electrical systems, their design and their normative and economic aspects.
Expected learning outcomes
Solving simple DC and AC circuits. Solving simple symmetrical and balanced three-phase systems. Basic knowledge of circuit topology, DC and AC systems, power factor correction, line losses and voltage drop. Design of a simple low-voltage distribution system. Basic knowledge of electrical safety. Basic knowledge of the economic aspects of electric energy.
Prerequisites / Assumed knowledge
Basic knowledge of algebra, geometry, mathematical analysis. Arithmetic of complex numbers. Basics of electromagnetism.
