Abstract
A fault detection system for detecting a fault condition on a direct current (DC) transmission line. The system may include a transmitter including a DC source to energize a transmission line and a receiver connected to the transmission line and including a signal generator to generate a periodic signal at or near a resonant frequency. The transmitter may include a termination impedance higher than a characteristic impedance of the transmission line to reflect substantially all the periodic signal to establish a standing wave on the transmission line. The transmitter may include a first fault detection circuit coupled to the transmission line to detect an amplitude attenuation of the standing wave of more than a threshold amount and, in response, to disconnect the transmission line from the DC source.
