浅谈互感器伏安特性试验装置的量值溯源

Discussion on the value traceability of current transformer volt ampere characteristic test device

本文从实际需求出发,针对此类仪器的主要技术参数,通过对电压与电流示值、互感器变比及极性、互感器基本误差、二次回路负载等主要测试项目的校准,依据国家校准规范编制的相关规定,制定了一套系统的校准方法,从而解决此类仪器的量值溯源问题。

In this paper,according to the actual needs,aiming at the main technical parameters of such instruments,through the calibration of voltage and current indication,transformer ratio and polarity,transformer basic error,secondary circuit load and other major test items,according to the relevant provisions of the national calibration specification,a set of systematic calibration method is formulated,so as to solve the problem of traceability of such instruments.
