Claim 11:
12. A method comprising
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, by a controller, the transmitting sensor to provide an alternating current (AC) test signal to the power channel, wherein the AC test signal comprises a predefined test signal pattern;
operating, by the controller, 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;
wherein analyzing the AC test signal to determine the fault in the power channel based on comparing the predefined test signal pattern with a predefined nominal probe signal pattern corresponding to a specific network configuration comprises:
transforming, using a continuous wavelet transform, the continuous power signal pattern to a first scalogram;
generating, using a machine learning model, a first feature vector comprising a plurality of features extracted from the first scalogram;
plotting the first feature vector in a feature space to determine the fault in the power channel.
