Abstract :
This paper presents the structure and use of a toroidal DC current comparator with a range from 50 A up to 1 000 A. The block arrangement is shown, and there is a description of the electronic circuits used in the feedback of the secondary current circuit. The paper concludes with an analysis of the uncertainties of the measured current and presents the results of our work.
