How to Solve Electrical Ground Loop Problems?
A formal definition of a ground loop that is very general is provided in IEEE Std. 100-1991, IEEE Dictionary as
Capacitive Coupling Effects
The fundamental principle invoked in shielding signal conductor(s) from external electric fields is that no substantial electric field can exist
