PROBLEM TO BE SOLVED: To provide an adaptor for current measurement which is easily attached to an existing electric apparatus that has been already installed.SOLUTION: An adaptor for current measurement is attached to a shell of an electric apparatus to be used. In a built-in current sensor 1, a pair of arm parts 2 protrudes from one end of a substrate, and the inner side of the pair of arm parts 2 is formed into a wiring insertion part 3 where an end part is open, and magnetic detection elements 4 are respectively disposed at the pair of arm parts 2. Since the end part is open in the wiring insertion part 3, it is not necessary to remove the wiring and cause the wiring to penetrate the current sensor as in a CT. |
