| 摘 要： | Rogowski线圈主要应用于脉冲大电流的测量,而电力系统中测量用电流互感器的使用环境中存在着诸多干扰。因而,要实现Rogowski对线圈工频稳态电流的准确测量,就需要了解Rogowski线圈对工频稳态电流的测量特性以及干扰对测量的影响。为此提出了一种基于磁动势平衡思想的Rogowski线圈动态控制模型,利用该模型描述了Rogowski线圈的一、二次侧各电气参量,并对互感器工频电流的稳态测量特性、干扰信号的影响作出了分析。

| Abstract: | Rogowski coil is applied in the measurement of large pulse current,however in the application environment of measuring current transformer there are a lot of interferences in power system,thus to implement accurate measurement of power frequency steady-state current by Rogowski coil it is necessary to understand the measuring characteristic of Rogowski coil and affects of interferences on measurement result.In this paper,a magneto-motive force balance based dynamic measuring model of Rogowski coil is propos... |
