Abstract
A power meter includes a current sensor sensing a current of a conductor signal transmitted along a conductor and outputting a current signal based on the current, a voltage sensor sensing a voltage of the conductor signal and outputting a voltage signal based on the voltage, and a controller receiving the current signal and the voltage signal and calculating a power factor of the conductor signal based on the current signal and the voltage signal. The controller determines an operating state of a powered device to which the conductor feeds the conductor signal based on the power factor.
