Podstawowym czynnikiem powodującym zwiększenie wartości błędów prądowego i kątowego dla transformacji składowych wyższych częstotliwości jest zjawisko dodatkowego odkształcenia prądu wtórnego przez indukcyjny przekładnik prądowy wynikające z nieliniowości charakterystyki magnesowania jego rdzenia magnetycznego. Głównym celem tego artykułu jest potwierdzenie, że dostępne na rynku indukcyjne przekładniki prądowe mogą zapewniać dokładną transformację wyższych harmonicznych pierwotnego prądu odkształconego.

EN

The primary factor causing the increase in the values of current error and phase displacement for the transformation of higher frequency components is the phenomenon of additional distortion of the secondary current by the inductive current transformer. It results from the non-linearity of the magnetization characteristics of its magnetic core. The main purpose of this article is to confirm that the inductive current transformers available on the market can ensure accurate transformation of distorted current harmonics.
