Course objectives:
|
During the course "Electrical Machines and devices Diagnostics" will be introduced to methods and system of diagnostics of electrical machines and devices. The particular sub-systems of electrical machines and diagnostic approaches of individual functional units of the electric machine will be presented to the students. The main space will be devoted to the understanding of the subject of diagnostics from the point of view of the strategy of machine operation and will be presented the key diagnostic methods for collecting information about the characteristics of the diagnosed machine system. In the course, the subject will also be devoted to the questions of the decision making processes when introducing a diagnostics system in the production and operation of electric machines. The questions of new and special diagnostic procedures in the diagnostics of electrical machines are realized especially in cooperation with practitioners.
