应用虚拟仪器技术，研制出一套适用于电流互感器稳态准确度和暂态饱和特性的检测系统。此虚拟检测系统具有测量、显示和分析等功能，并以数字和图形方式自动给出测量和分析的结果，适用于二次额定电流为5 A及以下各种类型电流互感器的检测。“,”Based on virtual instruments technique, a current transformer (CT) measuring system was developed.This system includes steady-state accuracy measuring andtransient saturation measuring. It has functions of measuring, display and analyzing. The results can be showed by digital numbers and diagrams. It can be used to measure any kinds of current transformer whose secondary current is below 5 A.
