Symmetry of single-phase loads in four-wire three-phase networks of alternating sinusoidal current

Abstract

To reduce losses in the zero conductor of threephase alternating current networks, it is proposed to use a switching device made on the basis of semiconductor thyristors, in order to enable the single-phase consumer to be connected to the required phase of power supply in order to reduce asymmetry. An algorithm for the operation of this device is developed and presented. Modeling of various schemes of connection of single-phase consumers allowed to make a conclusion about the expediency of the proposed measures.
