Educational goal:

The main course objective is to acquire knowledge about electric machines, their characteristics and methods of measurement and testing.

Educational outcome:

- the knowledge of all types of electric machines - the knowledge of methods for recording characteristics - the knowledge of methods and tools for checking parameters of electric machines

Course content:

Introduction (Basic types of testing. Testing during the production process, final testing. Official written documents during electric machine testing. General-visual machine examination.) Measuring the non-electric properties (temperature, velocity, momentum). Testing the transformator. (Routine and type tests. Tolerance. Checking the ferromagnetic core and oil. Measurement of winding resistance and checking the end marks and types of feedback. Short circuit experiment. Idling experiment. Dielectric strength experiment. Heating experiment.) Testing the asynchronous machines. (Routine and type testing. Tolerance. Idling experiment. Testing during the short circuit. Load method. Dielectric strength experiment. Determining mechanical properties.) Testing the synchronous machines. (Testing during production. Anchoring test. Idling experiment. Short circuit experiment. Properties of reactive load, regulation and external properties. Determining the reactance. Determining the changes of voltage and excitation current. Determining losses and efficiency.) Testing of DC machines. (Measurement of winding resistance. Determining the neutral zone. Idle testing. Commutation check-up. Determining losses and efficiency.) Testing of electrical generators.

Teaching methods:

Lectures are held using the modern learning resources.Testing the required knowledge before practice. Laboratory Practice-where students get the problem in advance and approach testing of el. Machines. Laboratory practice is assessed and the grade has an impact on the final course grade.
