Course content
Lectures 1. Introduction to the CAE design systems for electrical engineering design and description of its structure. 2. Requirements for electric light power and high power distribution. Types of heavy-current equipment. Types of electrical wiring. 3. Wires - dimensioning. Sizing of conductors. Wire resistance against short-circuit currents. Color coding of wires. 4. Theory of electrical protections. Types of protections and marking. Protection selectivity + model examples. 5. Electrical protection in the low voltage networks. Fuses, circuit breakers, overcurrent relays, RCD, power lines protection. Protection of electric motors. 6. Overvoltage protection of electrical equipment and data lines. 7. Device control design and control features. Switchboard measuring instruments. User friendliness. 8. Switching devices and contactors - parameters, specifications. 9. Power supplies. Low voltage network properties. Design of the size of the power supply. 10. Cooling of electrical equipment and switchboards. Types and requirements for passive and active cooling systems with or without filtration of the cooling medium. 11. Production and assembly of the low voltage networks. Testing of distribution devices. 12. Power distribution in buildings and industrial plants. Earthling in power distribution. 13. Documentation of electrical equipment. User manuals. 14. Problem-oriented computer programs to facilitate sizing, eg: device protection, line protection, documentation management. Practical classes: 1. Introduction of CAE system Eplan. Eplan modules and platform extensions, new trends of electric devices design and construction. Possibilities of standardization and automatic generation of scheme and documentation. 2. Eplan P8 installation, Eplan Docucenter installation, Eplan for Students installations, start up of new project (template selection), page types. 3. General device insertion, definition of properties. Design of scheme (angles, connections, interruption points). Scheme elements manipulation (copy, duplication, move), keyboard shortcuts, symbol macros, text functions (inserting, editing). 4. Navigators (graphical × functional point of view), terminals, connectors, cables, PLC cards. 5. Device concept, articles (management of article database, article assignment and selection). Wire numbering. 6. Automatic page generation, translations, reports, errors and warnings, data backup and exchange. 7. Submission of individual projects 8.-13.Solving of individual projects 14. Credit hour

Learning activities and teaching methods
Monological explanation (lecture, presentation,briefing), Self-study (text study, reading, problematic tasks, practical tasks, experiments, research, written assignments), Laboratory work

  • Preparation for exam - 10 hours per semester
  • Class attendance - 56 hours per semester
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.
Prerequisites
The knowledge of the circuit theory is recommended.

Assessment methods and criteria
Oral exam

Basic knowledge of the circuit theory.
