Abstract
PURPOSE: To automatically adjust the power-factor of a capacitor, by outputting a signal for cutting off the capacitor at night, not executing the closing operation at all, and executing the operation for outputting an automatic closing signal and an automatic cut-off signal of the capacitor in the daytime, in order to improve the power-factor.
CONSTITUTION: At night, a signal of the time switch 17 releases a reset state of the timer circuit 8 through the OR gates 6, 7, also a cut-off command signal is input to the ANd gate 10, the cut-off operation of the capacitor is executed, and the closing operation is not executed at all. On the other hand, in the daytime, the operation for outputting an automatic closing signal and an automatic cut-off signal of the capacitor for improving the power-factor is executed by the relation between a closing point and a cut-off point which have been set in advance, and the power-factor and reactive power of the circuit. In this way, the power-factor of the capacitor can be adjusted automatically.
