Abstract
PURPOSE:To prevent the repetition of an unnecessary tap switching action by operating the mean value of respective winding voltages at the secondary side and tertiary side of three-winding transformer and canceling the unbalance of respective voltages. CONSTITUTION:When the voltage of a secondary side winding 2 detected from the secondary voltage signal of a transformer 6 for a secondary side winding measuring instrument is in an action area in being dislocated from an LTC voltage setting value to a lower side by a fixed quantity and the voltage of a tertiary side winding 3 detected from the secondary voltage signal of a transformer 7 for a tertiary side winding measuring instrument is in a blind sector in being dislocated from the LTC voltage setting value to a higher side, a voltage control circuit 12 operates the mean value of the voltages of the windings 2 and 3. Thus, the unbalance of the voltages of the windings 2 and 3 is canceled. Only when the difference between the mean value obtained by the operation and the LTC voltage setting value exceeds the fixed quantity, a switching signal (a) is sent, and an on-load tap switching driver 8 is operated.
