一种改进的电磁式电压互感器励磁曲线的拟合方法

An Improved Method for the Fitting of Excitation Curve of Electromagnetic Voltage Transformer

介绍了一种改进的电磁式电压互感器非线性铁心励磁特性曲线的拟合方法，它既能使精度满足要求，同时因拟合过程人工干预少，使拟合过程较简单，拟合程序的实用性大为加强。

An improved method for the fitting of non-linear excitation curve of electromagnetic voltage transformer core is introduced in this paper, and it not only makes the precision meet the demands, but reduces the human factor influence as well. The method also is more simple and more practical.
