Course Description

Within the subject measurement methods for the measuring of the electrical and non-electrical quantities which are used in testing electrical machines will be covered, as well as standard testing methods and experiments for determination of the parameters of the electrical machines. Systems for monitoring and systems for the fault diagnostics of the electrical machines will be reviewed. The application of numerical models and methods will be demonstrated in order to prove the existence of the faults in the electrical machines.
