-In this paper a novel method for absolute calibration of the AC current comparator (or IVD) is proposed. An obvious advantage of this method is that the current comparator can be calibrated under practical working condition with an easy operative process and quite simple equipment. A comparison of the result by this method with that of the "bootstrap" method has shown that two methods may have similar accuracies with an order of 10-s (referred to the input) in the frequency range of 400 to 3000 Hz. In principle,...

本文提出一种新的交流电流比较仪及感应分压器的绝对校验方法,可在不改变实际工作状态的情况下进行校验,装置和操作程序都很简单。比较实验表明:在400~3000Hz频率范围内,它可以象参考绕组对检法一样达到10~(-9)量级的准确度(折合到输入端)。原则上讲,此法亦可用于直流分压器的校验。

In this paper two novel methods for absolute calibration of the DC voltage divider are proposed. An obvious common advantage of the two methods is that DC voltage divider can be calibrated under practical working condition with an easy operative process and quite simple equipment. A comparison of the calibration results between two methods has shown that they may have similar accuracies with an order of 10-7 for 100VDC.

本文提出两种新的直流分压器的绝对校验方法,它们都可在不改变分压器实际工作状态下进行校验,装置及操作程序也相当简单。在100V电压对同一分压器进行校验的对比实验表明,二者在10~(-7)数量级吻合。

Resently, the uncertainty of voltage ratio of a precise high DC voltage divider is determined by estimating the effects such as high voltage field, leakage currents, corona, temperature, ratio measurement at low voltage. By means of standard arms injection to measure the voltage dependence ratio variation, the uncertainty is hardly at the range of 10 -4 . The DC high voltage summation method is developed for measuring the voltage dependence ratio variation....
