I had another thought, take 1 of you RFI toroid and wind a 1 turn
primary on it, then terminate the secondary with a resistance equal to
the number of turns on the secondary. For example, on my T250 toroid,
I have 100 turns of wire, I would terminate it with 100 ohms. With a 1
turn primary this will give you a 1 volt per amp  current transformer.
