Subject aims expressed by acquired skills and competences

The object is engaged in changes of use qualities of materials, elements and systems which are used in electrotechnics and electronics. The object describes influences inductive of degradation of their functional properties and describes also means of negative action restriction of these influences. As next is the object engaged in servicing influence on the working life of electrotechnic machinery and also in methods for technical diagnostic that are used to determine of current quality of functional properties. The attention is also given to the electro-scrap, its collection, utilization and disposal of waste. The object is directed towards the student of master study, of branch: Electrical machines, apparatuses and drives, Electroenergetics, Commercial electrotechnics and also of other branches.
