Classification: CPC G  H | IPC G

Claim 0:
1. A system comprising:
a first power supply coupled to a power channel;
a load coupled to the power channel;
a transmitting sensor coupled to the power channel between the first power supply and the load;
a receiving sensor coupled to the power channel between the transmitting sensor and the load;
a controller in electronic communication with the transmitting sensor and the receiving sensor, the controller configured to:
operate 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;
operate the receiving sensor to sense, from the power channel, a continuous power signal including the AC test signal;
analyze 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 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 comprises:
transforming, using a continuous wavelet transform, the continuous power signal 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.
