一、前言国家计量研究机构最重要的任务是要确定各种计量单位。为了能在有关量限范围内用这些单位进行测量,就必须研究对这些单位进行倍数或分数的方法。所以,另一项重要任务就是提供高准确度的比率标准。交流电压方面最稳定和最精密的比率标准是感应分压器,它把一个整匝数转换成一个等效电压比率。电压比测量的结果是一个无量纲的数,所 I. Introduction The most important task of national metrology institutes is to determine various units of measurement. In order to be able to measure these units within the relevant limits, it is necessary to study ways of multiplying or fractionating these units. Therefore, another important task is to provide a high accuracy ratio. The most stable and most accurate ratio standard for ac voltage is the sense voltage divider, which transforms an entire turn into an equivalent voltage ratio. The result of the voltage ratio measurement is a dimensionless number
