Abstract :
NRC Electrical Standards Group is upgrading its shunt calibration facility to offer calibrations up to 100 A at 100 kHz. Primary standards of ac-dc current transfer difference have been verified using fast reversed dc source. A custom set of coaxial shunts has been built and is being characterized
