Content
The content of this subject is related to both electrical systems and installations.
Electrical installations:
The three-phase system with associated transmission and distribution networks, as well as associated switching facilities with transformers, lines/cables and other components. Analysis of stationary conditions that includes voltage drop and power calculations, inductance and capacitance in cables, as well as modeling of transmission lines. Load and short-circuit calculations including load distribution calculation of active, reactive and apparent power. Circuit diagram for electrical installations, including one-line diagram. Documentation in accordance with applicable norms and regulations. Introduction to the use of digital tools for calculation and simulation of electrical installations, including Febdok and PowerFactory. Practical laboratory work.
Installations: Low-voltage distribution systems (IT, TT, TN) with distribution and dimensioning of courses. Circuit drawing for electrical installations, including single-line and multi-line diagrams. Safety measures for installations with regard to safety for people, fire and operation, with a focus on induced voltages, overloads and short circuits. Calculation of overcurrent protection, earth fault protection and overvoltage protection. Regulations and regulations, including the Electricity Supervision Act, where the choice of cables, protection and installation techniques are central concepts. Risk analysis and documentation of installations, including measurement and troubleshooting. Practical laboratory work.
