A1

Disclosed is a power factor correction system. The power factor correction system comprises: a transformer part changing a voltage supplied from a power source to a load; a power changer part connected to a primary side and to a secondary side of the transformer part to receive voltage and current and selectively change the received voltage and current; a watt-hour meter receiving voltage and current from the power changer part, detecting power and a power factor on the basis of the received voltage and current, and outputting an on/off signal for correcting a power factor; and a power factor correction apparatus receiving the on/off signal and controlling the connection between a power factor correction device and the load to correct a power factor at the load.
