<p>PROBLEM TO BE SOLVED: To provide a current detector which only need be wound around current carrying lines to easily measure a current, and which can be composed to be compact and of low cost. SOLUTION: This current detector is provided with a tube 2 having electric insulation performance and flexibility, and a conductor 3 wound around an outer circumferential surface of the tube 2 at a constant interval to penetrate the tube 2 from its winding completing end to return to its winding starting end. The tube 2 is circularly wound around the energization ways 8a and 12a to compose a Rogowskii coil by the conductor wire 3, and the current flowing through the current carrying lines 8a and 12a is detected by this Rogowskii coil.</p> |
