Abstract: Systems and methods for health monitoring and fault detection in power distribution networks are provided. Aspects include providing a first power supply coupled to a power channel, providing a load coupled to the power channel, providing a transmitting sensor coupled to the power channel between the first power supply and the load, providing a receiving sensor coupled to the power channel between the transmitting sensor and the load, operating the transmitting sensor to provide an AC test signal to the power channel, the AC test signal comprises a predefined test signal pattern, operating the receiving sensor to sense, from the power channel, a continuous power signal including the AC test signal, analyzing, by the controller, the AC test signal to determine a fault of the power channel based on comparing the predefined test signal pattern with a predefined nominal probe signal pattern corresponding to a specific network configuration.
