Abstract
The new state primary standard for direct current is described, together with its block diagram and accuracy parameters. The accuracy of realization is improved by two orders of magnitude (standard deviation 5–10−8, residual systematic error 2·10−7). The range of current realization in the standardis extended to 10−16 A.
