Inductive voltage divider calibration with sampling method

This paper presents an automatic system developed at METAS for the calibration of inductive voltage dividers (IVD). The used method is primary for the n/10 ratio. With the described improvements, the calibration of IVDs has been made easier, faster and more reproducible than with the manual system u...

Description
Summary:This paper presents an automatic system developed at METAS for the calibration of inductive voltage dividers (IVD). The used method is primary for the n/10 ratio. With the described improvements, the calibration of IVDs has been made easier, faster and more reproducible than with the manual system used before. The uncertainties which can be reached with this new system are 28 times 10 super(-9) for the in phase and quadrature parts at a frequency of 1 kHz.
