Course abstract
Study course includes electrical grid structure 20 and the 0.4 kV network schemes and neutral operating modes, network neutral setting up of transformers, it overloads, switching apparatus, melting fuses, overvoltage surge arresters, circuit breakers, magnetic starters, toggle switches; voltage and power outages. Students acquire cable choice for acceptable voltage loss and allowable wire heating temperatures, the distribution network of electrical wiring and mechanical calculations, line design, construction, maintenance and repair; quality of energy.
Learning outcomes and their assessment
The student will be studying at the rate:
• Knowledge about the electricity supply system of agricultural structure, the conformation and the elements.
• Skills to calculate the electricity supply system of the elements required parameters (run cross-sections, fuses, circuit breakers and automatic switch rated current).
• Competence to assess the situation of agricultural electricity network, the network elements of the technica
