Power Plants and SubstationsCourse code: 120807 | 6 ECTS credits
Level of Studies:Undergraduate applied studies
Year of Study:2
Goal:The goal of the course is to educate students about design, planning and exploitation of substations as well as production of electrical energy, hydro- and thermo power plants.
Outcome:After exam passed, students should be able to control switchgear apparatuses adequately. Also, they should be able to know some elements of designing process of the substations, and to exploit substations and power plants.
Contents of the course
