Power losses in three-phase four-wire power system
Main Article Content
Abstract
In this article the expression for determining the relative power losses of three-phase four-wire supply system for non-sinusoidal asymmetrical mode under given load power factor and the known ratio of short-circuit power to active power load has been derived. The power factors and relative power losses for typical kinds of asymmetric loads and the power supply voltage were calculated.
