<p><P>PROBLEM TO BE SOLVED: To provide an energization information measuring device capable of changing the size of the whole body corresponding to a wire diameter constituting an electric path to be measured. <P>SOLUTION: This energization information measuring device includes: a magnetic field sensor 10; a first case part 20 for holding the magnetic field sensor so as to maintain a prescribed position relation to a primary conductor constituting an electric path 40 as a measuring object; and a second case part 30 arranged oppositely to the first case part 20, for holding the electric path so as to enclose it. The first and second case parts 20, 30 include first and second shield members 22, 32 comprising respectively a magnetic material having a U-shaped section, and each shield member 22, 32 is arranged oppositely so as to cover the electric path 40 and the magnetic field sensor 10, and each tip part is arranged in the shifted state so as to avoid facing, and the second case part 30 can be moved with respect to the first case part 20 so as to change overlapping of the first and second shield members 22, 32. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
