@cleedsYou don’t seem to understand what a ground loop actually is, and neither do you seem willing to understand it. So it’s no wonder that you’re confused about how to cure or prevent the problem.
"we can say a "ground loop" is formed whenever two or more grounds are at different potentials"
I don’t think so. From Wiki, "A ground loop is caused by the interconnection of electrical equipment that results in there being multiple paths to ground, so a closed conductive loop is formed."
