Electrical Current Measurement for Automated Testing Equipment

根据自动检测系统中电流测量技术极少被采用的现状 ,提出利用电流产生的磁场进行电流测量的概念 ,详细阐述了一种基于电子束在被测电流生成的磁场中发生偏转的原理进行测量的非侵入式电流传感器 ,并讨论了这种电流测量技术所面临的问题 ,提出了相应的解决方案。最后提出有关电流数据和其他相关信号的分析方法以及电流测量的意义。

In practice electrical current (EC) measurements are very seldom performed. For this reason, we present a concept of current measurement technology of using the magnetic fields created by a flowing current. The theory of the proposed nonintrusive sensor is the measured deflection of a beam of pulsed electrons, due to the magnetic fields created by a flowing current in a conductor. Then we described the limitations of the technology, and presented the corresponding solutions. At last, the analogy of the current data and other correlative signals are discussed. And then draw a conclusion of the characteristic of the technology.
