The power factor and efficiency of the three-phase power systems with linear asymmetric load
Main Article Content
Abstract
This work analyses the influence of the asymmetry of the three-phase circuit linear load and the power loss in the neutral wire of four-wire power supply system on the power factor and the efficiency. The new formula of the approximate dependence of the three-phase system from the power factor, which can be used for the valuation of the improvement of the energy characteristics of the electrical power system provided by the reactive compensator or the active filter. The identity of the taken out formulas is checked by the comparison of the exact and the approximate dependence of efficiency of the supply system from the quantity of resistance loss for the uniform of unbalanced load with different ratio of resistances.
