电流互感器二次负载校验软件开发

Development of examination software for secondary load impedance in current transformer

针对电流互感器10%误差下的二次负载阻抗校验,介绍10%误差曲线的现场测试及二次负载校核方法,并在此基础上开发电流互感器二次负载校验软件,实现电流互感器二次负载校验的自动化。应用实例表明,该软件计算结果真实、可靠,实用性强。

Aiming at the current transformer, this examination of secondary load impedance with the paper introduces the onsite test of 10% error curve largest allowed ratio of error, 10%, in and the examination of secondary load impedance, on the basis of which develops the examination software realizing the automation of secondary load im- pedance examination in current transformer. The application of the software shows that its calculation result is authentic, reliable and practical.
