| Course abstract | |
| The aim of the study course is to gain the skills to use transformer power choice methods, taking into account the specificity of the load type; schemes of power stations and substations; short-circuit current calculation methodology; the conditions under which to select substation equipment; electric power loss calculation methodology in substations. | |
| Learning outcomes and their assessment | |
| Knowledge - on the transmission network structure, construction and the elements, the types and importance of power plant and substation to the power supply.
Skills - to make the necessary electrical parameters calculations and estimates to choose the transmission equipment facilities (transformer, circuit breakers, etc.). Competence - to evaluate power supply equipment conformity to engineering calculations from the point of view of the technical and economic aspects in the project phase and in operation phase. |
