Subject aims expressed by acquired skills and competences

To inform students about electromagnetic disturbance and with possible ways of its elimination. After subject graduation the student will be able to identify, outline and decode disturbing influences in electrical networks and to interprete measured results in relation to valid standards and rules including of solving finding for disturbance elimination and their comparing.

Summary

Student will be informed about special terminology and basic definitions and with kinds of disturbances. Rules and standards of EMC are also included into subject contents and also possible ways of active and passive elimination of disturbances.

Compulsory literature:

Subject syllabus on web sites of K 420: http//fei.vsb.cz/kat420 Wakileh, G.J.: Power Systems Harmonics.

Recommended literature:

Fuchs, E.F., Masoum, M.A.S.: Power Quality in Power Systems and Electrical Machines.

Way of continuous check of knowledge in the course of semester

Reports from each measurement processed on the base of measured values from these measurements and their subsequent processing, completing and assessing. Continuous verifying of student knowledge in the numerical exercises in a form of debate and inquiries to achieve student active participations in study process. Identify, deduce and search of problem solving and their interpretation by students. Test from numerical exercises, eventually from chosen theoretical circuits Term project on a given theme on the basis of selection, investigation, ordering and final compilation of facts and their processing into final form of given theme.
