منبع ترانسفورماتورهای جریان الکتریکی، تغییرات خواص مترولوژی را برای تبدیل جریانهای تحریف شده انجام می دهد

The aim of the paper is to present results explaining the phenomena of the inductive current transformers (CTs) metrological properties deterioration for the transformation of the distorted currents. In the article the influence of the conductive disturbances on their accuracy of transformation of the distorted signal is described. Analysis of the results from the laboratory studies show, that conductive disturbances in the CT primary current, in some measuring conditions, cause increase of the current error/ratio correction factor and phase displacement/phase angle of transformation of the main harmonic of distorted current.
