i want to step down a high-current before applying it to a CMC.

i believe i can do that the normal way:
  1. first pass the high-current through a current transformer. (say, 1A down to 1mA).
  2. and next pass the 1mA output and my 1mA comparison signal into a CMC.
Correct?

Is it possible to combine the CT and CMC into a single device? I was thinking a CMC with non-1:1 ratio might be possible.
