As shown in this figure, the trauma probe 20 has a drive motor 3, 3 on the top of a main body 1 made of an aluminum alloy, drive rollers 2, 2 rotated by the drive motor 3, 3, and the drive rollers 2, 2. A movable auxiliary roller 4, 4 is installed below, and a lead-in wire (not shown) is sandwiched between the drive roller 2, 2 and the movable auxiliary roller 4, 4.

  Specifically, the front and rear movable auxiliary rollers 4 and 4 are connected by a spring 8a, and connecting pieces 8b and 8b connected to the rotation shafts 4a and 4a of the movable auxiliary rollers 4 and 4 are connected to the handle 8, When the handle 8 is moved up and down, the rotary shafts 4a and 4a of the movable auxiliary roller move up and down along the arcuate grooves 8c and 8c.

  Therefore, in order to hold the lead-in wire between the driving rollers 2 and 2 and the movable auxiliary rollers 4 and 4, the handle 8 is once moved upward and between the driving rollers 2 and 2 and the movable auxiliary rollers 4 and 4. A space into which a lead-in wire can be inserted is formed, and when the handle 8 is moved downward after inserting the lead-in wire here, the movable auxiliary rollers 4 and 4 are moved upward, and the driving rollers 2 and 2 and the movable auxiliary rollers 4 and 4 The lead-in wire is held between the two and is held by the bias of the spring 8a.

Next, the operator on the ground operates the remote control operation device to turn on the power source of the trauma probe drive motor and the pump.
Then, the trauma probe starts to run on the lead-in line from the vicinity of the house to the utility pole. At this time, the water in the water tank is supplied from the pump to the contact A and the contact B, and moisture adheres to the outer surface of the lead-in wire. Since the voltage between the outer surface of the lead-in line and the ground is measured by a digital voltmeter, moisture enters the lead-in line when the lead-in line is damaged, and the voltage at that place increases. The data measured by this digital voltmeter is sent from the transmitter to the receiver on the ground, and further sent from the receiver to the personal computer, where the data is analyzed to identify the position where the lead wire is damaged. .

That is, the lead-in wire is usually a single-phase 2-wire, 3-wire, or 3-phase 3-wire, one of which is grounded but the other is not grounded. If the ungrounded line is damaged, the voltage is measured between the exposed conductor of the damaged part and the ground. Since this voltage fluctuation is minute without a dummy grounding electrode, the outer surface of the insulator body is covered with aluminum foil as shown in the figure, and this aluminum foil is not in contact with the wire, and the scratched part is exposed. The voltage between the aluminum foil is measured via the conductor and moisture. With this configuration, the voltage fluctuation increases, so it is easy to distinguish it from noise, and even if the distance between the trauma probe and the ground receiver and personal computer is wireless, the trauma of the wire can be accurately detected.
