| 摘 要： | 在进行TA（电流互感器）5%误差曲线测试时，发现用OMICRON TA测试仪得出的数据失真。利用TA励磁曲线数据，重新对5%误差曲线进行了手工计算，得出了矫正后的数据曲线。通过对不同TA测试数据的分析和对比，指出此测试仪在5%误差曲线绘制时可能存在拟合错误。

| Abstract: | This paper introduces a 5%error curve test case of TA （current transformer） in a power plant and finds that there is data distortion obtained by OMICRON TA tester. By using excitation curve data of TA , 5%error curve is manually recalculated and data curve after correction is then obtained. By analyzing and com-paring different TA test data, the paper points out probable matching error while the tester draws 5% error curve. |
