Abstract
A low-frequency AC power standard based on the programmable Josephson voltage standard (PJVS) has been developed at the National Research Council of Canada. At the step voltages, PJVS provides quantum accuracy. Differential digital sampling is used to extend the quantum accuracy to the AC power standard output voltage and current, nominally 120 V and 5 A. The paper describes the power standard and its evaluation.
