摘　　要：为了解决现场电流互感器(CT)试验存在的人机交互界面操作不便,系统、算法存在局限性和时间的延迟性,数据不可靠性和数据采样点不够精确,结果分析误差较大和人为因素权重影响较大,不能形成完整的试验报告和满足现场新老CT试验设备,降低试验设备购置成本等问题,本文基于MATLAB编程语言中的GUI界面图形处理,开发出了满足电力系统现场CT试验应用软件。In the field test of current transformer （ CT）, the existing problems are those as below ： the man - ma- chine interaction interface is unhandy to operate; system and algorithm have limitations and time delay; unreliabili- ty of data exists and data sampling points are not accurate enough ; the error of result analysis is larger and the man - made factors weigh more ; test report is unable to be generated imperfectly, old and new field CT test equipments are not compatible with the test and purchasing costs of test equipments are hard to be reduced. In order to solve these problems, the field CT test application software is developed based on the GUI interface graphics in MATLAB programming language to satisfy power system.
