<p>PURPOSE:To clearly identify a wiring spot and to minimize a possibility of errorneous wiring, by a method wherein secondary terminals of both side-phase current transformers are placed in a direction perpendicular to that of a secondary terminal of a central phase current transformer. CONSTITUTION:A power source bus and a cable head are connected to upper conductors 11A-11C and lower conductors 12A-12C of 3-phase. Central phase conductors 11B and 12B extend upward and downward, respectively. Both side- phase conductors 11A, 12A, 11C, and 12C extend in a direction perpendicular to that of the central phase conductors 11B and 12B, and in the same direction as that of the central phase conductor in the middle thereof. In case wirings are conducted from each secondary terminal to a protection relay, and meters via a control line, connection spots to their respective sencondary terminals are different from each other, which results in clearly identifying each position of the secondary terminals.</p> |
