I assumed the ground potential stays the same between 2 points, but have there been any studies to see if it's actually DC, or if there's an AC component to it? If there's an AC component in the ground at either end (or both) that may introduce EM into adjacent pairs across the cable. And are they more or less than the EM ungrounded pairs would pick up?
