中文摘要:
      电磁式电流互感器谐波传变特性复杂多变,传变误差难以估计。设计了铁磁性材料磁滞回线的观测实验,分析了磁滞回线形状对电流互感器谐波传变误差的影响。针对谐波误差检测精度要求高的难点,研制了高精度的电流互感器谐波误差检测系统,并通过实验分析了频率、负载、基波电流、谐波相角、直流分量对电流互感器谐波传变误差的影响。
英文摘要:
      The harmonic transfer characteristics of electromagnetic current transformer is complex, and the transfer error varies and is hard to estimate. This article designs the experiment of hysteresis loop of ferromagnetic material, and analyzes the influence of the hysteresis loop shape on the transfer error of current transformer. Aiming at the difficulty of high accurate detection of harmonic error, a high precision detection system of current transformer harmonic error was developed. With the experiment, the influence of frequency, load, fundamental current, harmonic phase and DC component on the harmonic transfer error of current transformer is analyzed.
