Etalonarea canalelor de transmisie cu fibra optica din transformatoarele electronice de masurare a curentului

Abstract

Precise measurement of currents and voltages in the presence of intense electric and magnetic fields requires to adjust transmission channel parameters. The best results are obtained if the measuring signal is converted into frequency modulated signal and it is transmitted through fiber optic link from measurement point to monitoring point. The paper presents the working principle and structure of a instrument current transformer and the method for adjusting the parameters of transmission channel.
