Abstract

At National Institute of Metrological Research (INRIM) a Selectable Value High DC Voltage Standard operating in the range from 10 V to 100 was realized to cover the absence of high level DC Voltage Standards at voltages upper than 10 V to employ both as Laboratory Standards or traveling Standards for Interlaboratory Comparisons. It A novel ground-mobile electronic technique was utilized. In the first tests the developed Standard showed better noise and stability of the same order of top level DC Voltage and Multifunction Calibrators, widely employed in Electrical Calibration Laboratories. The project is also upgradable up to 1000 V.

Keywords
