ことを特徴とする自動力率調整装置。 In an automatic power factor adjustment device that measures the power factor of an electric power system and adjusts the power factor by turning on or disconnecting a power factor improvement capacitor based on the measurement result, the current and voltage of the electric power system are adjusted. a power factor measuring section that calculates the power factor of the power system based on the current and voltage taken in by the input section; a comparison section that compares the power factor value before the power factor improvement capacitor is turned on or cut off based on the output of the power factor measurement section and the power factor value after the power factor correction capacitor is turned on or cut off; and a comparison result of this comparison section. The power factor improving capacitor is characterized by comprising a turning on/off control section that returns the power factor improving capacitor to its original state if the power factor value before turning on/off the power factor improving capacitor is good based on Automatic power factor adjustment device.
