Abstract
A binary type self calibrateable AC current comparator (CC) was developed at NMIJ. In order to confirm the reliability of the new AC current ratio standard at NMIJ, a bilateral comparison was conducted with NRC using an error compensating current transformer. The paper describes an error estimating procedure for the CC and the results of the bilateral comparison
