<p>PROBLEM TO BE SOLVED: To shorten restoration time by reducing climbing frequencies for specifying an electric pole with a possibility of having a failed facility, and specifying the electric pole with the possibility in an early stage.SOLUTION: A current measuring instrument 1 for a standing body has: core sensors 13 and 23 which are constituted by performing windings 12 and 22 to arc-shaped magnetic cores 11 and 21; first and second holder parts 10 and 20 which form a pair with core covers 14 and 24 to be covered with the core sensors; and a measuring instrument body 30 which rotatably supports the first and second holder parts by approximating one ends to each other, and measures current on the basis of detection signals detected by the core sensors. In closure time when the other end sides of the first and second holder parts are butted to each other, a space 51 forming an approximately annular shape and in which an electric pole 50 can be placed is formed, and the current which flows via the electric pole placed in the space is measured by the measuring instrument body. The measuring instrument body is provided with an extensible member 35 which adjusts an installation height position to the electric pole.</p> |
