<p><P>PROBLEM TO BE SOLVED: To provide a current transformer for measuring instrument for easily changing a profile of a coupling body in accordance with the wiring mode, accurately measuring currents flowing into the wires, and for avoiding possibility for damage of the coupling body. <P>SOLUTION: The current transformer 5 for measuring instrument to detect currents flowing into wires is provided with a coupling body 3. The body 3 is constituted by joining each other a plurality of core units 1 having a housing 7, an iron core 9 provided within the housing 7, and a coil 11. The core unit 1 can be easily mounted and removed to and from the other core units 1, and is also engaged with each other to freely rotate. When each core unit 1 is coupled with each other to form the coupling body 3, the wires are surrounded with the coupling body 3 to easily detect the flowing currents. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
