Study Guide

Objective

The student:
- knows and can describe the requirements for electrical installations
- is able to define general characteristics of electrical installations
- is able to describe different protection methods
- is able to choose electrical equipment
- can carry out checks before commissioning

Content

Requirements relating to electrical installations (planning and ensuring the protection requirements).

Definition of general characteristics (maximum load and equalization of load, distribution system, electrical system compatibility, safety system)
Protection methods (base protection, fault protection, overcurrent protection, overload protection, short-circuit protection)

Selection and installation of electrical equipment electricity (protection classes, choice of wiring, different types of wiring, external influence, wiring load capacity, voltage drop, protective devices, overcurrent protection, overvoltage protection, protection conductor design, potential equalization)

Controls (pre-commissioning inspections, inspections, testing, maintenance checks)

Assessment methods and criteria

The main basis for the grade in the course is determined by the points in the course stent. The course element consists of questions that are answered in writing and calculations.
The laboratory work and the reports are assessed and can increase or decrease the grade from the exam.
