Transformers and electric machines (5 cr)

Evaluation scale

0-5

Objective

The student masters the basic structures, operating principles and equivalent circuits of the most common industrial dc and ac motors. The student is familiar with the operating characteristics and possible applications of the various motor types. The student is able to interpret standard symbols describing the performance characteristics and structure of motors and is familiar with the excitation systems used in generators and the protection methods of generators. The student is also familiar with the control circuits of electric motors and the components used in them. The student knows the basic transformer types and their operating principles and applications, and protection methods.
