This paper introduces a new strategy to reduce the phase unbalance of line currents in the three-phase four wire distribution networks and reducing the magnitude of neutral current by flat 50%. The proposed approach executes phase balancing by introducing new winding connections in the ordinary two-winding transformer and therefore it provides switch-less operation. The proposed approach is self sufficient and robust in itself such that it may relieve SCADA to take care about the phase unbalance produced in the distribution systems. The effectiveness of the proposed approach has been implemented on several load conditions. The simulation results show that the proposed approach is efficient and promising for phase balancing in distribution networks.
