Abstract

PURPOSE:To always hold a proper line voltage, by controlling the line voltage of a feeding circuit having different degrees of fast and slow motions of voltage fluctuation by means of a common line voltage controller. CONSTITUTION:The line current has a sudden and quick increase due to a sudden fluctuation of load caused at a feeding circuit 1B, and the output side voltage of a line voltage controller lowers. In such case, a voltage detecting circuit 5 produces a detection signal to start a delaying circuit 6. At the same time, a current relay detect an increase of the line current and immediately transmits a signal to a switching circuit 8. Thus the circuit 8 works to supply the 2nd control signal e2 obtained at an output terminal 7b of a voltage relay 7 to a line voltage controller 2. Accordingly the controller 2 performs a control immediately in case when the circuit 1B has a sudden fluctuation of load to cope with a sudden fluctuation of voltage.
