Abstract :
The need of calibrated inductive voltage dividers (IVD) with the smallest possible uncertainties was appeared for determination, maintenance and dissemination of the ohm and the farad in audio frequencies. In this paper an IVD calibration system that is based on bootstrapping method is described and the preliminary results and improvement efforts are mentioned. The relative uncertainty of the system from the preliminary results is 2.10/sup -8/ for the inphase component, 5.10/sup -8/ for the quadrate component at 1 kHz.
