数字式钳形电流表示值误差测量不确定度评定与表示

Assessment and Representation of Uncertainty in Measurement of Digital Clamp Ammeter Indication Error

数字式钳形电流表主要由一块电磁式电流表和穿心式电流互感器组成,用于测量正在运行的电气线路的电流大小,可以在不断电的情况下测量电流。本文介绍了数字式钳形电流表示值误差测得值的不确定度分析与评定。

The digital clamp ammeter is mainly composed of an electromagnetic ammeter and a through core current transformer,which is used to measure the current of the running electrical circuit,and can measure the current under the condition of continuous power supply. This paper introduces the uncertainty analysis and assessment of the digital clamp ammeter indication error.
