OVERVIEW

Teaching provides the students with the fundamental concepts regarding the electrical macro-components responsible for the generation and use of energy. In particular, the teaching furnishes basic knowledge about structure, operating principles and electrical models of transformers and rotating machines in steady state conditions. Thanks to classroom lectures, numerical exercises resolution and laboratory experiences, students learn procedures to forecast the behaviour of such electrical macro-components in different operating conditions.

AIMS AND CONTENT

LEARNING OUTCOMES

Aim of the course is to provide the students with basic knowledge of physical structure, operating principles and electrical models of the most important electrical machines.

AIMS AND LEARNING OUTCOMES

The aim of the teaching is to provide the students with basic knowledge of physical structure, operating principles and electrical models of the most important electrical machines in steady state conditions from the electrical and/or mechanical point of view.The goal of the teaching is to improve the skill of the students in harmonizing the knowledge gained in previous years as far as mathematics, physics and electrotechnics are concerned, and the one dealing with electrical machines theory, to be able to model those macro-components to forecast their performances in civil and industrial applications.

PREREQUISITES

Basic concepts related to complex numbers, analytic geometry, mathematical analysis, differential calculus and general physics.

TEACHING METHODS

Classroom lectures and numerical exercises resolution, laboratory experiences.

Students with valid certifications for Specific Learning Disorders (SLDs), disabilities or other educational needs are invited to contact the teacher and the School's contact person for disability at the beginning of teaching to agree on possible teaching arrangements that, while respecting the teaching objectives, take into account individual learning patterns.

EXAMS

EXAM DESCRIPTION

Written and oral exams.

Written exam: 2 problems concerning transformers and rotating machines, duration 2 hours. 

Oral exam: 2 questions concerning transformers and rotating machines, duration of about 75 minutes.

ASSESSMENT METHODS

The aim of written and oral exams is to evaluate if the candidate has understood the operating principles of the electrical machines and is able to solve simple numerical examples. During oral exam candidate ability in clearly describing concepts and using correct and suitable technical wording will be evaluated as well.
