Lectures Design rules for electrical equipment Safety elements in electrical engineering Practical classes: 1. Electricity distributions in civic facilities, the FVE scheme 2. Selection of contactors, measuring the dependence of contactor pull-up time on position 3. Contact point resistance, design and use of connector for long life, measurement of contact resistance of oxidized contactor and metal samples 4. Dimensioning of the wires, checking the current path (cable and terminal block/connector) with a thermal camera/pyrometer. 5. Measurement of RCD in the presence of the DC component and pulse interference. 6. Measurement of arc protection relay 7. Setting up and testing MainsPro electronic protections 8. Measurement of overvoltage protections (opening voltage, parasitic leakage current) 9. Measurement of power supplies - ripple, regulation accuracy for output current and input voltage, dynamic behavior, behavior during overload/in current mode. 10-14. Lightning rod mini project.

Learning outcomes
|
This course consists from theory of general electrotechnics design and practical using of CAD/CAE system ePLAN. Lectures focus on electric power distribution, conductor dimensioning, principles and using of el. protections, switching devices, surge arresters, power supplies using and other switchboard design activities. Practical lessons covers learning of ePLAN system. Students will make individual project including documentation.
Students get basis of electrotechnics documentation generation at practical lessons. The teaching is based on CAD/CAE system ePLAN. Teacher leads collective project at first part of the course, than students work on individual projects.
