Determination of the high-voltage dependent of fluke 792A at NIM

摘要

This paper describes a method of using inductive voltage divider (IVD) to determine the voltage dependence of voltage ac-dc transfer standard of Fluke 792A at voltage above 200 V and at frequencies of 50 kHz and 100 kHz. The evaluation of the voltage dependence of the ratio error of IVD and the test set-up are described and the preliminary results are reported.
