摘要

本文根据IEC 44-1和44-6的要求，采用幅值(比)误差、峰值瞬时误差、相位误差和复合误差等多种二次电流计算方法，研究和评价电流互感器畸变参数对其性能的影响。这些参数包括:多重短路电平(Isc/IR)、二次负荷值和类型、直流分量(X/R比和故障始角)、剩余因数(Kr)和内外谐波。

Evaluation of current transformer performance in the presence of remnant flux and harmonics

This paper studies and evaluates the effect of current transformer (CT) distortion parameters on its performance using various secondary current calculation methods according to IEC 44–1 & 44–6 like: magnitude (ratio) error, peak instantaneous error, phase error and composite error. These parameters include: multiple short circuit level (Isc/IR), secondary burden value & type, DC component (X/R ratio & fault inception angle), remanent factor (Kr) and both external & internal harmonics.
