Electrical Engineering

Aim

To give knowledge about the design and use of electrical power equipment used in mechanical engineering. In the end of the course the student should know about how to:

• perform calculations on symmetrical and unsymmetrical three phase systems
• perform calculations on three phase transfomer and draw complex circuits per phase
• understand the princip function and perform calculations on the DC-machine
• understand the princip function and perform calculations of the asynchronous machine
• perform calculations and phase control of inductive loads with capacitors in Y-or D connected
• perform calculations in power electronics with thyristors and diodes and rectifier AC-current with two-three and sexpuls bridges
• understand the princip function and perform calculations in speed control of the DC-machine
• understand the princip function and perform calculations in speed control of the asynchronous machine
• understand the princip function of the synchronous machine
• understand and know personal danger in electrical systems Course content three-phase systems three-phase transformer three-phase power distribution DC-machine asynchronous machine speed control of DC and AC- machine synchronous machine phase control of reactive loads AC/DC-conversion personal danger Teaching and working methods Lectures, exercises and laboratory work.

The examination language relates to the teaching language as follows: If teaching language is Swedish, the course as a whole or in large parts, is taught in Swedish. Please note that although teaching language is Swedish, parts of the course could be given in English. Examination language is Swedish. If teaching language is Swedish/English, the course as a whole will be taught in English if students without prior knowledge of the Swedish language participate. Examination language is Swedish or English (depending on teaching language). If teaching language is English, the course as a whole is taught in English. Examination language is English. Other The course is conducted in a manner where both men's and women's experience and knowledge are made visible and developed. The planning and implementation of a course should correspond to the course syllabus. The course evaluation should therefore be conducted with the course syllabus as a starting point.
