The course objective is to study basic concepts about time constant and time variable electrical currents, about electricity and electrical properties of materials. Besides, the objective is to present the way of operation of electrical energy system and electric machines (ways of operation, principles, types etc.), as well as the possibility of their application in the modern electric motor drives, that is, in the systems of environmental protection (removal of smoke and harmful gasses, removal of waste waters, transport of hazardous materials etc.). The objective is to present phenomena which have an impact on the electric environment and the living environment due to PES operation and electric consumers, as well as the modern standards and methods of protection.

Students will be able to understand basic concepts about time constant and time varying electric currents. They will master the concepts about electricity and electric properties of materials. They will be able to understand the way of operation of power electric systems and their main consumers (electric machine etc.). They will be able to apply modern electric machines and electric motor drives in the environmental protection systems (removal of smoke and harmful gasses, removal of waste water, transport of hazardous material etc.). They will understand the phenomena which have an impact on the electric environment and the living environment and will be able to apply modern standards and methods of protection.
