As a large number of intelligent devices are put into use,the demand for power supply quality is getting higher and higher.The current supply voltage of the grid fluctuates greatly,which can not meet the needs of end users.Aiming at the shortage of the existing power supply and distribution,this paper develops a new voltage regulation technology which installs on-load tap-changer in 10 kV dry type transformer.The real-time on-load voltage regulation can improve the quality of terminal power consumption,so as to achieve stable operation of output voltage within the set range,and play the effect of protecting electrical equipment and saving energy.
