Department of Electric Drives and Traction

Synopsis:

The course conveys knowledge on the basic functions and service characteristics of electrical power engineering main components. It deals with electric energy sources and appliances: transformers, power inverters, generators, chemical and photovoltaic sources, DC and AC motors. The course notifies of contact electric apparatus, of generation, transfer and distribution electrical energy including electrical apparatus protection. Problems are test in the laboratory by line voltage.
