Precise locating of cable faults in fixed-point cable faults Rough distance measurement in fixed-point power cable fault testing is very easy, just use a cable fault distance finder. If the main unit of the cable fault tester is used for rough measurement, it generally only takes a few minutes to measure the rough distance from the power cable fault point to the cable test end, and the rough measurement error generally does not exceed ten meters. Therefore, the rough measurement distance of power cable fault is not the main difficulty of cable fault detection.
A large number of power cable fault tests have proved that the problem of precise location of power cable faults has become the main difficulty in quickly finding and testing power cable faults. That is to say, the specific cable fault location is the most critical step in the cable fault test. Now more and more cross-linked cables are used, and most of the cable faults of the cross-linked cables are closed faults, and the discharge sound of the cable fault point is often in ten. Several meters or even tens of meters have almost the same loud noise, which brings great difficulty to the cable fault location. In addition, in the actual cable fault location, since the tester is far away from the test end, when the cable fault point has not been heard. When the earthquake waves are emitted, the mood is often anxious, and even the high-voltage discharge equipment is suspected of not working. Sometimes it is necessary to know whether the sound wave heard by oneself is synchronized with the discharge cycle of the discharge equipment in the interference background of the pulse sound source, otherwise the final judgment cannot be made.
The cable fault locating instrument adopts the combination of advanced analog low-noise design and high-performance filter circuit, and adopts the method of acousto-magnetic synchronous locating, which greatly improves the anti-interference performance of the cable fault locating instrument. The exquisite assembly process makes the cable fault locator have the highest level in China. It can accurately locate all kinds of cable faults, especially for cross-linked cables and cable-enclosed cable faults, which has a unique test effect. It is the latest replacement product in the cable fault test instrument.
