Abstract
This paper is focused on active and reactive power consumption and power losses in the consumer power system depending upon supply voltage quality. Supply voltage level deviations from rated voltage affect directly power consumption and power losses in the consumer power system. Active and reactive power relation to supply voltage is characterized by load factors. In the paper a practical method for determining the load factors of active and reactive power in relation to supply voltage is described. Also harmonic distortions of supply voltage and current affect power losses and need more attention in the consumer power systems.
