Course abstract

The aim of the study course is to acquire with the correlations between the life cycle and economic efficiency of electrical equipment, learn the methodology of economic calculations. Gains knowledge about the application of the results of the analysis of energy efficiency parameters in the operation of electrical equipment. Acquires practical skills in determining the energy and economic parameters of the equipment and skills to perform their analysis in order to justify rational methods of operation of the equipment, to develop plans for their replacement, reconstruction or restoration of working capacity.

Learning outcomes and their assessment

Knowledge - knows factors influencing energy efficiency, life cycle indicators of electrical equipment, principles of efficient operation.
Skills - calculate the efficiency of the use of electrical equipment and the energy efficiency and economic parameters of the operation of electrical equipment.

Competence - economically sound assessment of the life cycle, energy efficiency and economic performance of existing and planned electrical equipment.
