DEVICE FOR INSPECTING FAULT POINT OF DISTRIBUTION LINE

PROBLEM TO BE SOLVED: To provide a fault point inspection device for distribution lines capable of measuring a change in a magnetic field at a position apart from a distribution line. SOLUTION: An electric loop wire 110 allows a current according to a change in a piercing magnetic flux density to flow round, when magnetic flux generated by applying a pulse voltage to the distribution line pierces it. A current transformer 120 detects the value of the current flowing in the loop wire 110, from a change in a magnetic field generated by the loop wire 110. An indicator 130 indicates the detection result of the current transformer 120 by changing the number of LEDs turned on among five. COPYRIGHT: (C)2007,JPO&INPIT
