摘要

本文提出了一种在高达1000v电压下直接标定电阻分压器电压的新方法。采用高稳定性的电感分压器和具有稳定交直流电压比差的电阻分压器组合，将直流电压比从约瑟夫森电压标准传递到被测分压器。该方法允许完全自动化，并有可能实现$0.1\ \mu\ mathm {V}/\ mathm {V}$数量级的测量不确定度。

A New Method for Precision Calibration of Resistive Voltage Dividers up to 1000 V

The paper presents a new method for direct voltage calibration of resistive voltage dividers at voltages up to 1000 V. A combination of a high-stability inductive voltage divider and a resistive voltage divider with stable ac-dc difference of voltage ratio are used to transfer the dc voltage ratio from a Josephson voltage standard to the divider under test. The method allows full automation and has a potential to achieve measurement uncertainties of the order of $0.1\ \mu\mathrm{V}/\mathrm{V}$.
