Vliv transformátoru na přenos neharmonických napětí

Abstract

The aim of this diploma thesis is to confirm the influence of the transformation of non-harmonic voltages during transmission from the primary side of the transformer winding to the secondary and vice versa. The experiment took place in two phases. First, an experimental measurement of its behavior after applying a harmonic voltage with a frequency of 50 Hz was performed on a real transformer under laboratory conditions. A transformer model was then created from the measured values in the LTspice simulation program. Pre-formed non-harmonic voltage waveforms were applied to the winding of the simulated transformer. After this simulation phase, the same non-harmonic voltages were applied to the windings of the real transformer and measured. The result of both parts of the experiment is made in clear graphs and tables.
