Sažetak
This article examines issues related to power quality and generation of higher harmonics in single-phase transformers of low power supply, supplying electricity to household, office and industrial equipment. A simulation of the generation of higher harmonics of these transformers was performed based on the results of the analysis of the magnetic field using the Finite Element Method (FEM). Harmonic composition of the current in the primary side was determined using a Fourier transform applied to the curve of the current obtained through the analysis of the magnetic field using FEM. The results were fully confirmed by the experimental study of the harmonic composition of the current in the primary side of the investigated one-phase transformer using a digital oscilloscope. The used approach is unique, and it enables manufacturers to explore the harmonic composition during the design stage, and take appropriate measures to reduce their magnitude.
