Abstract: PROBLEM TO BE SOLVED: To inspect parallel cords for electric currents flowing through the cords by detecting the lines of magnetic force generated by the electric currents with a magnetic detector holding the cords with a clip and displaying the state of the detected signal and, at the same time, sending the signal to the outside. SOLUTION: By holding parallel cords 10 with the clip of a main body unit, lines of magnetic forces 24 and 24' are generated from the periphery of each conductor from the electric currents 23 and 23' flowing through the cords 10 and offset with each other. The cords 10 are held between E-shaped cores 6 and 6' and the lines of magnetic force are detected with a coil 26 when the cords 10 are exclusively used for an alternating current or with a magnetic detector 7 provided with a magnetic detecting element when the cords 10 are used for a direct current. The detected signal is sent to a comparator through a differential amplifier, a filter circuit, and a rectifier circuit and the comparator inspects the detected signal by comparing the signal with a preset value and displays inspected results on a display.  The display lights in accordance with the magnitude of the measured current and the lighting state of the display can be transmitted to a remote place through an optical fiber. Therefore, the energized state of electric equipment can be confirmed safely and surely without giving such a change as the disconnection, etc., to the equipment.
