  • Fault detection for DC power lines based on detected frequency response changes
    Patent number: 12775052
    Abstract: A fault detection system for detecting a fault condition in a direct current (DC) system. The system may include a transmitter including a DC source to energize a cable and a receiver connected to the cable and including a signal generator to generate a periodic signal. The transmitter may include a termination impedance matched to the characteristic impedance of the cable to absorb substantially all the periodic signal. The transmitter may include a fault detection circuit coupled to the cable to detect changes in the frequency response of the cable by tracking changes in the envelope of the power of the periodic signal and outputting a fault signal if the rate-of-change of the envelope of the power of the period signal exceeds a threshold level.
