High perfomance selectable value transportable high dc Voltage standard
At National Institute of Metrological Research (INRIM), a selectable-value
Transportable High dcVoltage Standard (THVS) operating in the range from 10 V
to 100 V in steps of 10 V, was developed. This Standard was built to cover the
lack of high level dc Voltage Standards at voltages higher than 10 V to employ
as laboratory (local) or travelling Standards for Inter-Laboratory Comparisons
(ILCs). A ground-mobile electronic technique was used to enhance the accuracy
of the THVS at the higher values. The THVS shows better noise, better
short-mid-term stability than top level dc Voltage and multifunction
calibrators (MFCs) and better suitability and insensibility to be transported
than these instruments. The project is extensible to 1000 V
