Abstract :
This paper introduces the work to establish AC voltage standard at mV level at frequency 1kHz, 20kHz, 100kHz and 1 MHz using inductive voltage dividers (IVDs) as the ratio references at NIM. Methods to determine the ratio errors of IVDs, to evaluate the voltage dependence of IVDs and to measure the loading effect are described in this paper
