ETeh4060 [GETH4061] Electric Equipment Usage Economics
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.
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.

Part time studies:
All topics specified for full time studies are accomplished, but the number of contact hours is one half of the number specified in the calendar.
Developed and successfully defended course work.
Evaluation of the quality of the developed course work (max. 50%) and the knowledge shown in the defense of the work (max. 50%): mark (on a 10-point scale)
Students developing the course paper independently, guided by the knowledge gained in lectures and practical work, uses the indicated or other available sources of information.
Course work quality assessment:
1. Evaluation of work quality: 9 points, - there are all necessary sections/volume); there are no serious problems in the text, there are slight defects in the images and the text; 6 points, - basic requirements are met; there are some vague or erroneous statements in the text, there are minor shortcomings in the formatting; 3 points: basic requirements are not met; there are significant errors in text and formatting shortcomings.
2. The assessment of an answer: 9 points: correct answer with minor imperfections / errors: 6 points: answer that contains correct basic concepts, but without explanations or contains significant errors: 3 point: the answer is incorrect, there are serious errors: 0 points.
