Bildungsziele
The aim of the course is to provide the most significant elements on the applications of electrical engineering concepts. Students will learn the basics of electrical systems, machines, converters and plants, also dealing with the related safety issues. By means of case studies, energy efficiency and costs aspects will also be considered, considering both classical and innovative applications. Knowledge and understanding: • Master the most important concepts about industrial electrical applications • understand the design principles of electrical equipment and installations. Applying Knowledge and understanding: • Using proper criteria and tools for designing or choosing electrical systems and devices. The elements learnt are applied to real world case studies. Making judgments: • Ability to select the more adequate electrical system for a certain industrial application. Communication skills: • Acquisition of the field related technical terminology. • Ability to describe the state of the art of the technology adopted in electrical industrial systems. Learning skills: • Ability to learn autonomously is improved by acquiring analytical approaches, inter disciplinary skills and by reading and understanding scientific and technical documentation.

Art der Prüfung
The assessment of the course is by a written exam and a quiz. The written exam comprises 3 numerical exercises, one about the design of an electric line, one about the choice of an electric motor for a specific application, and one chosen from one of the following topics: i) dc machines; ii) static converters; iii) harmonic suppression. The quiz part consists of 20 generic theory questions covering the theoretical part of the course (multiple choice, open answer, true or false). - Formative Assessment: nof foreseen - Summative Assessment: 50% written exam, exercises: 3 exercises (3 hours); ILOs assessed: 1 ,2, 3, 4; 50% written exam, theory: 20 multiple choice questions (1 hour); ILOs assessed: 5, 6.

Bewertungskriterien
Final mark, 50% written part, 50% theory questions. Relevant for assessment: correctness and clarity of written answers, correct exercise results, proper explanation of the assumptions.
