摘　　要：本文对有源电子互感器的工作原理、结构特点进行介绍,并提出电子互感器的测试方法,该测试系统采用高精度模拟量采集、转换模块及同步信号时钟源,能够对全系列、各类型电子式、电磁式、电容式互感器进行测试;不仅适用于在实验室互感器本体进行测试,还适用于现场对电子互感器及其采集器、合并单元、甚至整个数据传输通道的数据准确性、一致性进行测试。通过实验室及现场比对,该系统性能稳定,测试结果正确。Introducing the principle and structural characteristic of fountainous electrotransformator in this article, and bring forward the testing technique of electro-transformator. The testing system with the high-precision simulative quantity collection,switching module, synchronous signal and timepiece,be able to test all series and all type electro-transformator ,electromagnetic transformator and capacitive transformator. Be the same with testing transformator at noumenon in the laboratory, and testing data veracity and consistency of the electro-transformator and its collection,incorporate cell ,the whole data transmit chunnel out of doors. Passing contrastive testing that in the laboratory and out of doors,the result of the system is that the capability is steady and the testing result is correct.
