Calibration of inductive voltage dividers at power frequencies using an AC-PJVS

This paper describes a method for the calibration of inductive voltage dividers (IVDs) at power frequencies using an AC-program Josephson voltage standard (AC-PJVS). The IVD is used in the primary ac power standards based on a sampling measuring system. Because the AC-PJVS is operated automatically by a computer program, the measurement procedure is more straightforward than that of conventional step-up methods.
