Field of use of magnetic current transformers in electric power industry

Abstract

Traditionally, current transformers are used to measure current in elements of electric power systems and construct relay protection for these elements. However, the main disadvantage of current transformers is the restriction on the installation caused by the need for tie-in to the measured circuit where the conductor has considerable dimensions, over which large currents pass. This drawback is devoid of magnetic current transformers of various types. In the paper, the features of the construction of the current conductors of various industrial enterprises are considered and recommendations are offered on the choice of the location of the magnetic current transformers on these current conductors.
