Abstract :
Current comparators have been used to make possible the direct intercomparison of AC-DC transfer devices having widely different current ratings with each being operated at its nominal full scale level. The results are in close agreement with the differences obtained by build-up methods involving a succession of devices having nominal current ratings in the ratio 2:1 or less.
