Abstract

A distribution transformer tap changer with continuous operation of tap changing and control of the secondary voltage brings a remarkable improvement in power supply quality, keeping the voltage in the net constant. Design and practical evaluation of the electronic tap changer for a three-phase 10 kV distribution power transformer are described in the paper. Finally, its technical and economical feasibility in the distribution network is studied.
