Use of an inductive divider for AC voltage ratio calibration

This paper presents the calibration of an electronic voltage divider and precise instrument voltage transformers in the range up to 1 kV at 50 Hz frequency using inductive voltage dividers. We also describe a way to evaluate the difference between a standard inductive divider and a calibrated instrument voltage transformer or electronic voltage divider expressed as the ratio error and phase displacement. The paper also presents the construction of a standard decadic voltage divider with a range of input voltage (10×100) V and (10×10) V.
