Product Description

Description

The cable fault locator uses the principles of vibration pickup and electromagnetic induction to determine the specific location of the cable fault point. A high-voltage pulse generator is used to cause flash over discharge at the fault point. Physical phenomena such as vibration waves, sound waves, and electromagnetic waves generated by the flash over discharge at the fault point are picked up by a special probe of the pointing instrument, amplified, processed, displayed, and output by the cable fault pointing instrument. The precise location of the fault point is determined by the tester's hearing and vision. That is, the task of accurately locating the cable fault point "directly above the cable and within the range of rough measurement" is completed.
This fixed-point instrument is suitable for low-resistance, short-circuit, open-circuit and disconnection faults of power cables, high-frequency coaxial cables, street light cables, and buried wires made of various materials with different cross-sections and media, as well as high-resistance leakage and high-resistance flash over fault.

Instrument layout and instructions
Composition of the instrument
1. Cable fault locator: accurately locate cable fault points within the rough measurement range.
2. Probe: including probe, probe, three claws, and connecting rod, connected to the input channel to receive signals.
3. Wear headphones; connect the input channel of the pointing instrument (feedback of the output signal).
4.7-core signal line: connecting cable between the pointing instrument and the probe (connecting the pointing instrument and the probe).
5. Charger: Connect to the charging socket of the instrument for charging.
6.A frame: used when testing using the step voltage method.
7. A-frame connection cable: cable fault locator and A-frame connection cable.
8. Ground pin: A matching accessory for the A-frame.

Packing list

Once the A-frame is connected, it will automatically enter the test interface as shown on the right.
Notice that at the bottom of frame A there are arrows, red and green, with red at the front and green at the back. This means that red indicates the end of the cable and green indicates the beginning of the cable.

Slowly move the A-frame along the cable burial path towards the end of the cable and observe the changes in the red and green bar graphs on the test screen. This reflects a change in the direction of the current.
At a great distance from the point of damage, the red and green bars on the screen appear slightly irregular and small.
When you get close to the fault point, for example about 5 meters from the fault point, you will notice that the red bar graph becomes very large, as shown in the image above on the left.
When you are directly above the fault point or approximately 1-2 meters in front of and behind the fault point, you will notice that the red and green bar graphs become very small and appear on the screen as shown in the image on the right above.
Once you pass the fault point, for example about 5 meters from the fault point, you will notice that the green bar graph becomes very large.
This way, by searching patiently, you can find the location of the fault.
