There are many small details to pay attention to in the use of a cable fault tester. A cable fault tester is an important tool for maintaining all kinds of cables. The intelligent cable fault tester adopts a variety of fault detection methods and applies contemporary advanced electronic technology achievements. There are many small details that need to be paid attention to in the use of the calculation cable fault tester. The cable fault tester is an important tool for maintaining various cables. The cable fault intelligent tester adopts a variety of fault detection methods, applies contemporary advanced electronic technology achievements, adopts computer and special electronic technology, and combines the company's long-term successful experience in developing cable testers. A generation of high-tech products.
The cable fault tester adopts the modern classic DC high voltage flashover method, impulse high voltage inductance sampling method, impulse high voltage current sampling method, low voltage pulse method and other test methods. It is suitable for measuring various sections, different media and various materials. Low-resistance, short-circuit, open-circuit and disconnection faults of power cables and high-frequency coaxial cables, as well as high-resistance leakage and high-resistance flashover faults. It can also be used to detect the short circuit, open circuit and mixed line fault of the local telephone cable, and can also check the whole length of the cable. The cable fault tester finds out the cable fault method: 1. With high pressure equipment, there are traditional impact high pressure flashover method and low pressure pulse method.
2. Any high-resistance fault presents simple waveform characteristics similar to low-voltage pulse short-circuit faults, which are very easy to interpret. 3. The cable fault tester finds the fault point through four main parts: the cable fault ranging host, the locator, the path meter, and the high-voltage signal generator. As the name suggests, the cable fault tester is an important new type of detection tool that uses a variety of fault detection methods to check line faults and maintain various cables.
It can be said to be an intelligent product, an efficient and intelligent high-tech product. When using the cable fault tester, we must pay attention to some details, and I will introduce it to you. 1. You cannot just rely on the data obtained by the instrument to make judgments, but also need to take into account the actual situation, such as historical faults, and the situation of the joint.
2. If suspicious points are observed on the surface of the cable, the correct record after the installation and laying of the cable is completed should be consulted. 3. The precise position of the tee joint, the direction of the cable path, in the underground relationship, the situation of a cable to other cables or joints, and the precise position of the two cables with different cross-sectional areas to the joint. When operating and using the cable fault tester, you must pay attention to the details. It is related to the problem of accuracy, and you cannot completely rely on the cable fault tester. In some places, you still need to check it yourself before you can rest assured.
