1. A computer-implemented method of facilitating separately-sourced redundant power feeds to a system, the computer-implemented method comprising:

obtaining voltage waveform data for power feeds connected to the system;

determining for the power feeds, using the obtained voltage waveform data, multiple respective signal characteristics for each power feed;

comparing the multiple respective signal characteristics of the power feeds to obtain multiple characteristic differences between the power feeds;

determining, for each characteristic difference of the multiple characteristic differences, whether the characteristic difference exceeds a respective difference limit;

for each characteristic difference exceeding its respective difference limit, providing a corresponding weight score to obtain a weighted characteristic difference score;

obtaining a total characteristic difference score by summing the weighted characteristic difference scores;

determining that the power feeds are not separately-sourced redundant power feeds connected to the system based on determining that the total characteristic difference score does not exceed a set threshold score representative of separately-sourced redundant power feeds; and

based on determining that the power feeds are not separately sourced power feeds, initiating a corrective action to ensure that the system is connected to separately-sourced redundant power feeds.
