Abstract :
The paper describes a set of four cylindrical, coaxial, ac current shunts used as the new National Research Council (NRC) working standards in the frequency range up to 100 kHz. They were designed for currents from 20 A to 100 A. At the lower current range the shunts were compared to NRC coaxial shunts built from discrete resistors. At the higher current range they were compared to the old working standards, a set of commercial shunts. The paper presents the description of the shunt design as well as results of their experimental performance and uncertainty evaluation.
