| Abstract: | The paper mainly discusses the principle,design and calibration of high-accuracy and multi-range AC resistance voltage divider,which the range is from 0.5V to 600V and the frequency is up to 1MHz.Based on the existing technology,the AC voltage proportional measurement range is expanded and applied.The calibration test of the high-accuracy AC voltage divider is realized through the broadband AC-voltage-sampling measurement and synchronous-sampling trigger technology,and a gain-buffer-amplifier matched with the rear-impedance of the voltage divider.After the test verification and summary,the uncertainty of the proportional measurement ratio error of the voltage divider reaches 5×10-6~5×10-4(k=2).The uncertainty of phase angle error is up to 5μrad~1mrad(k=2). |
