摘要
采用标准互感器法校准钳形电流表时,计量标准不确定度来源于相关的互感器变比系数与输入电流。本文介绍了避免相关的方法,提供了间接测量时不确定度评定的范例,为相关人员开展不确定度评定提供借鉴。
When calibrating clamp ammeters using the standard transformer method,the uncertainty of measurement standards comes from the related transformer ratio coefficient and input current.This article introduces methods to avoid related issues and provides an example of uncertainty assessment in indirect measurements,which can provide reference for relevant personnel to carry out uncertainty assessment.
