But you said what I wanted to hear - don't take it all back!!!

I think Dwayne interpreted me more correctly.  I'm looking to keep these
other systems isolated from the Power system.  Not just because of noise,
but because it's possible that they are connected inadvertently and I don't
need to let magic smoke out of somebody else's equipment, let alone mine,
by picking up "ground" in different places.

What I need is some way to measure the Power parameters without being
electrically connected, in a way of thinking.  I would opto-isolate if
necessary, etc, but that gets into other problems (like real estate).
