Question: What are the reasons for inaccurate cable fault location? Answer: Cable fault is the most common power fault in power repair, and it is more troublesome to detect. Although the application of the cable fault detector has greatly improved the effectiveness of cable fault detection: What are the reasons for the inaccurate cable fault location? Answer: Cable fault is the most common power fault in power repair, and it is more troublesome to detect. Although the application of the cable fault detector has greatly improved the efficiency of cable fault detection, the positioning accuracy of the cable fault detector will also be affected by certain factors when the cable fault detection work is carried out in some complex environments.
So what are the factors that affect the positioning accuracy of the cable fault detector? We all know that the resistance value of the fault point of the cable is the most important factor affecting the fixed point of the cable fault detector, especially the low resistance fault of the cable, the more troublesome the fault point positioning. Because the smaller the resistance value of the fault point of the cable, the smaller the sound when the high-voltage signal generator is used for high-voltage impact, the more difficult it is for the locator to function, and the locator for metallic short-dead faults has no effect. The second is the cable laying environment. At present, most of the cable laying methods use the cable trench laying method, but the cable laying route in the cable trench is relatively short, and the cable fault detector will be interfered by other cable lines when locating the fault point.
Or because the faulty cable is not threaded, if the fault point is discharged to the air, the pointing instrument is not easy to receive the sound signal. The last is the interference of the surrounding sound. We all know that when the cable fault detector locates the fault point of the cable, the signal sound of the fault point is relatively weak, and a quiet environment is needed to monitor it. If the surrounding environment is too noisy, it will affect the Signal snooping at the point of failure. When the fault detector is locating the fault point, it will be mainly affected by the above aspects.
In order to ensure the accuracy of cable fault location, we should be patient and careful to accurately locate the cable fault point.
