Abstract
This paper deals with Power Quality (PQ) issue in Low-Voltage (LV) network. It is focused on harmonics' spread and its impact on consumers. The paper introduction concerns with general resources and impacts of the worse Power Quality in network, especially in the area of harmonics. Besides this, it concerns with their occurrence, their superposition and calculation method of Total Harmonic Distortion (THD), but mainly there are standards which apply to Power Quality and are valid in the Slovak Republic. Next part contains data from one-month measurement which was carried out with PQ analyzer in village on the border. The values were chosen from this measurement in the area of harmonics measurement and their impact on consumers in the Czech Republic who are supplied from the Slovak Republic. Measurement values were used for the simulation where the situation is analyzed in detail. The paper includes identified shortcomings and initial recommendations for the power quality improvement in the given area.
