Abstract :
The Ac-dc transfer project at NIST is expanding the use of inductive voltage dividers (IVDs) for the calibration of high-voltage ranges of thermal voltage converters (TVCs) and digital voltmeters (DVMs). We report on a system to facilitate the comparison of the frequency coefficients between two ranges of TVCs or DVMs to the frequency coefficient of an IVD ratio
