Erik Dierikx, Faisal Mubarak and Joop Dessens "An automated set-up for calibration of inductive voltage dividers" Submitted for publication in the Proceedings of the 2012 Conference on Precision Electromagnetic Measurements, Washington, US (July 2012).
An automated system has been built for calibration of inductive voltage dividers (IVDs) in the frequency range from 50 Hz to 10 kHz. In this system, computer controlled IVDs are used to automatically find the in-phase and quadrature bridge balance. Initial tests at 1 kHz have shown an agreement with results from previous calibrations within the estimated uncertainties of 1.0 × 10-7 V/V in-phase and 1.0 × 10-6 V/V quadrature.
