Development of a precision resistive voltage divider for frequencies up to 100 kHz

Abstract

A range of precision resistive voltage dividers for use in high frequency power standards is currently under development at the National Measurement Institute, Australia (NMIA). The paper describes the design of the resistive voltage divider (RVD) and the methods of its evaluation. The target uncertainty in the voltage ratio is 100 µV/V at 100 kHz for both amplitude and phase at voltages up to 240 V.
