Course detail
Low Power Electrical Sources
FEKT-MMZEAcad. year: 2018/2019
The course is focused on the use of small power sources in terms of sustainable development. They are specified the possibility of using solar, wind and hydro plants in our country with according to applicable law. It is also clarified the issue of cogeneration of low power and possibilities of using other alternative sources of energy, such as heat pumps, Stirling engines and fuel cells.
