摘要
介绍感应分压器分压比的一种测量方法,提供了具有等分抽头的感应分压器分压比的测量线路,并对此测量线路进行了全面而细致的分析.通过计算及有关实验,得出了该测量系统的总误差:无论是比差或是角差,其测量的绝对误差均可小于5×10^(-8)(对于输入端而言).
In this paper, the author introduced a method of intrinsic stand-off ratio of the induced voltage divider, provided a measuring circuit for intrinsic stand-off ratio of the induced voltage divider with uniform tap, and made an detailed analysis for the measuring circuit. The author obtained total error of the measuring system by making computation and experiments. The absolute measuring error of either ratio error or angle error is less than 5×10-8. (for the input)
