电子式互感器数据分析系统的设计与应用

Design and Application of a Data Analyzing System of Electronic Transformers

在分析电子式互感器的工作原理及其数字信号输出格式的基础上,详细设计并实现了基于WinPCap网络工具包的新型电子式互感器数据分析系统。该系统可对采样报文进行精确的实时捕获分析,并以动态波形图的方式显示瞬时的采样波形,为电子式互感器性能测试、极性校验等系列试验提供了有效的辅助分析工具。

First the operation principles and digital output protocol of electronic transformers are analyzed, based on which a new data analyzing system of electronic transformers is designed in detail and implemented which, in turn, is based on a WinPCap toolkit. This system is capable of accurate real-time capturing analysis of sample packets while displaying the transient dynamic waveforms, providing an effective auxiliary and analytic tool for electronic transformer performance test, polarity verification and so on.
