摘要
利用LabVIEW虚拟仪器设计平台,提出了基于虚拟仪器的光纤电流感测系统。该光纤电流感测系统利用法拉第效应来感测电流所产生的磁场强度,具有无磁滞、饱和之限制,性能足以满足电流感测系统,适用于大范围电流变化值之测量。通过虚拟技术对待测电流的波形亦可直接观察,并可读出,可方便进行波形显示、电流分析、储存及处理。
VI measure system of fiber-current sensor was brought forward using VI designed platform of LabVIEW. This system is used to measure magnetic field of current in virtue of Faraday Effect. It possesses advantages of non-hysteresis, non-saturation and large-scale current measurement. Wave form of current could be observed directly by virtue of virtual-instrmnent technology. Measure data could be displayed, analyzed, stored and disposed easily.
