Abstract:
This paper has a purpose to explain the concept of harmonics at Low Voltage Supply Systems, which are part of the Power Quality Measurements. The work describes the main sources of the harmonic voltages and currents, the effects of harmonics, and the objectives of power quality measurement. In this work are given also the values of individual harmonic voltages in percentage of the nominal voltage correspondent to EN50160. It is shown and described the block diagram of analog front end circuit for measuring the harmonics of three phase 4-wire power supply network. The results of all studies are explained and the conclusion is made at the end of the paper.
