On the Debugging Method of Cable Fault Tester

The cable fault tester can debug low resistance, short circuit, open circuit, high resistance leakage and high resistance flashover faults of various power cables below 35KV. It can debug the open circuit and short circuit faults of communication cable, control cable, signal cable, street lamp cable and local telephone cable. The length of various cables can be debugged and calibrated. It can adjust the propagation speed of radio waves in the cable. Cable fault tester debugging cable fault type: â—Ž it can debug low resistance, short circuit, open circuit, high resistance leakage and high resistance flashover faults of various power cables below 35KV. â—Ž open circuit and short circuit faults of communication cable, control cable, signal cable, street lamp cable and local telephone cable can be debugged. â—Ž the length of various cables can be tested and calibrated. â—Ž debugging method of cable fault tester capable of testing the propagation speed of radio wave in cable: â—Ž pulse method (debugging the full length of open circuit, short circuit, low resistance and open circuit fault distance of cable); â—Ž flashover method (debug high resistance leakage fault and high resistance flashover fault of cable); Characteristics of cable fault tester: â—Ž it has traditional pulse method and flashover method. â—Ž adopt 14.1 "Large screen LCD touch screen is used as the display terminal. The waveform is clear, the simulated touch key operation on the interface, the key definition is simple and clear, and the operation is very simple and fast. â—Ž the fault can be judged by debugging waveform to ensure the correctness and readability of debugging waveform. â—Ž the instrument works on WIN2000 platform. It has user-friendly software and full Chinese menu, very friendly man-machine dialogue and powerful data processing function. The dedicated database can store any number of debugging results. â—Ž with extremely safe sampling high voltage protection and isolation measures, the commissioning instrument will not crash and damage in the rated impact high voltage environment. â—Ž the success rate of fault detection, debugging accuracy and debugging convenience are better than any domestic detection equipment of the same kind. â—Ž it has a standard USB interface, which can easily connect the printer, standard keyboard, USB flash disk and upgrade the equipment software. â—Ž because there is no mechanical keyboard, it has simple operation and high reliability. â—Ž single end commissioning distance is 16km, and there is no commissioning blind area.

Theory of Cable Fault Locator
The basic function of cable fault locator is in the power industry and some industries using cables, especially in some complex power systems. It is very difficult to find the fault of underground cable lines. However, in this regard, the continuous emergence of equipment with various functions and simple operation can not only reduce the high cost of fault detection, but also reduce the inevitable long-time power failure when difficult to find (cable fault locator) cable fault, which brings a lot of convenience to troubleshooting. Direct buried cable fault detection in underground direct buried cable and underground residential power distribution (URD) system is a very time-consuming thing, and will cause very inconvenient power failure to users. Some technologies may also damage the cable. For some equipment with high technical requirements, its operation is more complex, and only operators with strict training can use it, which brings a lot of inconvenience to the popularization and application of this kind of technical equipment. Therefore, the selection of appropriate technology depends partly on the knowledge of cable system design understood by the designer of fault detector, and also partly on the professional and technical knowledge of equipment and operators in this regard. With appropriate equipment and professional technology working on site, it is the first step to detect faults quickly and effectively. Hammering (pulse) method many power companies use hammering (pulse) method. This technique is effective in detecting high resistance faults in a simple (cable fault locator) cable system. The hammering method includes using a pulse or impulse voltage to impact the power cut cable. When an effective high voltage pulse strikes the fault area, the fault point flashover and produces a hammering sound that can be heard by the operator along the cable surface. However, detecting cable faults often requires several hammers, and repeated shocks may damage the cable.
