Abstract
The paper describes a new ac-dc current shunt calibration system with a testing current range of 1 mA to 100 A and frequency range 10 Hz-100 kHz. The new system consists of a USB controlled ac-dc comparator and a set of reference coaxial shunts with dedicated thermal voltage converters. The design of custom build shunts has been optimized through theoretical modelling. The results of experimental performance of the new calibration system will be presented
