| Course abstract | |
| The aim of the study course is to acquire with the economic efficiency of electrical equipment operation, the life cycle of electrical equipment, learn the methodology of economic calculations. Students gain knowledge of energy efficiency parameters analysis and application in electrical equipment operation, evaluation and analysis of individual electrical equipment technological operations databases. During practical work the students acquires skills in calculation of energy and economic efficiency, application of the principles of economic cybernetics, analysis and optimization of management systems for equipment operation. | |
