Study Guide

Objective

fter completion of the course the students understand how electrical energy is produced, transmitted, distributed and balanced, and know the most common parts of the electrical system of buildings. The students recognize the differences between direct and alternating current and their use in electric power technology. The students also know the operating principles of electric machines and the control of machines using power electronics.

After completion of the course the students understand the fundamental need of presenting the voltages, currents, powers etc.as complex variables and are able to apply these to the basic theorems of electrical engineering (ohm’s law, Kirchoff’s laws etc.). The students understand the concepts of complex power and are able to analyze the power levels based on complex voltages, impedances and currents. The students are able to analyze more complex circuits using the superposition principle and source transformations. The students understand the concepts of amplification, attenuation and their dB representations. The students are able to conduct attenuation / amplification / frequency response measurements at the electronics lab using an oscilloscope and a function generator.
