Abstract

PURPOSE:To obtain the core for three-phase current transformer economically having uniform current transforming characteristic by associating the first F-shaped core components and second F-shaped core components in a confronting manner as a core having three windows. CONSTITUTION:Two F-shaped core structures 11 are associated in a confronting manner to thereby produce a core plate 12, and the core plates 12 are then laminated alternately as turned at 180 deg. to one another. Thus, only one die is required when the structure 11 is produced to be economic, and the structure 11 can be also associated uniformly. In addition, no difference in laminated thickness occurs, no foregin material is mixed therewith, and the core having uniform characteristics can be stably produced.
