Abstract
We describe the construction of two-stage, amplifier-aided current transformers (CTs) and their use to characterize AC-DC transfer shunts up to 100 A at 100 kHz. Tests show that the frequency coefficients of the CTs have small changes with current level. This level independence of the frequency coefficients for the CTs is used to characterize the frequency coefficients of the shunts up to 100 A and out to 100 kHz in terms of measurements at 20 A.
