Abstract. In the elaboration, levels of supply voltage at the ends of loaded low-voltage lines were statistically evaluated, describing them using basic statistical measures and examining the frequency distributions. Levels of voltages and time of their occurrence on the background of current regulations were also assessed. It was found out that in spite of the fulfilment of statutory requirements electricity consumers complained about the poor, in their opinion, quality of the voltage.
Key words: low voltage networks, supply voltage quality
