Complex Error Measurement and its Validation Method by Equivalent Circuit Parameters Measurement for Wideband Resistive Voltage Dividers

Abstract

Resistive voltage dividers (RVDs) have a wide range of use in volage measurements. It is due to their simple structures and applications under both DC and AC conditions. We have been developing a highly accurate and wideband RVD and its error measurement method from industrial frequencies to MHz ranges. In this paper, complex errors could be measured by the method up to 100 kHz. To confirm that the result is valid, a new validation method has been proposed where accurate equivalent circuit parameters can be measured, and a valid complex error can be determined. Also, we discussed the problem that avoids an accuracy degradation of the parameters through a comparison between the measured error result and the calculated result by the proposed validation method.
