  • Frequency selective power monitor
    Patent number: 10158400
    Abstract: A power line carrier fault detection system includes a forward signal generator configured to transmit a carrier signal to a power line. A directional coupler couples the forward signal generator to the power line. The directional coupler is configured to separate forward and reflected power. A frequency selective filter associated with the directional coupler is configured to meter frequencies within a band of a transmitted carrier signal and to attenuate out of band signals.
