摘要
介绍了电子式互感器现有的测试方法,并提出了不足之处。针对这些不足,提出了一种测试电子式互感器暂态性能的方法,给出了测试原理,并结合某变电站实验室联调实例,利用该测试法对电子式互感器的暂态特性进行了测试,对发现的一些问题进行了总结。该方法能够真实反映电子式互感器的暂态性能,对出厂检验或现场调试都具有一定的指导意义和参考价值。
This paper introduces the existing testing method of electronic instrumental transformer, and points out its de- ficiencies. For this issue, a test method of transient performance is presented, and the test principle is given, combing with an instance about a substation, using the method to test the transient performance of electronic instrumental trans- former in laboratory, some problems are found in a summary. The method truly reflects tronic instrumental transformer, and has a certain signficance and reference value for the filed. transient performance of elec- factory inspection or debugging in
