Rozbor problematiky napěťové nesymetrie

Abstract

The aim of the thesis is to define what voltage unbalance is. The first part defines the calculation of voltage unbalance and various ways to decrease it. As the main sources of the unbalance electric arc furnace and a single-phase electric traction 25kV/50 Hz, their description and possibilities to decrease it in practice were chosen. In the second part, a bar chart illustrates actual measured values from distribution networks in certain part of the Czech Republic and the voltage unbalance is determined.
