Abstract
A device load consumes power supplied from an AC power supply. A bypass circuit is provided in parallel with the device load. A controller controls current flowing through the bypass circuit so that an identification signal indicating information for identifying an electric device is superimposed on current flowing from the AC power supply to the electric device. A power measurement sensor detects the current flowing from the AC power supply to the electric device. A control device identifies the electric device based on the identification signal superimposed on the current detected by the power measurement sensor.
