Final report on supplementary comparison EUROMET.EM-S23 (EURAMET project No 815): Bilateral comparison of inductive voltage divider

This report presents the results of a bilateral comparison of the measurements on an inductive voltage divider within the framework of EURAMET. The aim of the project is a comparison of AC voltage ratio measurements between INM, Romania, and VSL, the Netherlands. Measurements of the decade ratios 0.1, 0.2, ... 0.9 were performed at the following frequencies and voltages: 55 Hz/5 V, 400 Hz/10 V and 1 kHz/10 V. The agreement between the results from both laboratories is well within 0.2 x 10... V/V for the in-phase ratio deviations and within 1.0 x 10... V/V for the quadrature deviations.
