罗氏线圈电子式电流互感器谐波测试方法研究

摘要

Introduction was made to the harmonic requirements of transformer from the national standard and the Rogowski coil electronic current transformer principle. This paper summarized the simple and useful method of harmonic measurement of Rogowski coil electronic cur-rent transformer. Harmonic testing of electronic current transformer could be carried out with the high precision harmonic sources and standard current transformer and transformer calibrator. The results show that this method has strong applicability and simple operation, which greatly enriches the testing method of harmonics.%介绍了国家标准对互感器谐波要求和罗氏线圈电子式电流互感器原理，总结了罗氏线圈电子式电流互感器谐波测量的简单实用方法，通过高精度谐波源配合标准电流互感器和互感器校验仪对电子式电流互感器进行了谐波测试。结果表明：该方法适用性强，操作简单，极大地丰富了谐波的测试方法。
