An overview of the precise location method of cable faults The touch screen cable fault tester produced by Shenzhen Noyafa uses the embedded computer for measurement control and data processing. The entire operation is carried out under the Windows interface, and the 10-inch touch screen displays an overview of the cable fault precise location method. The touch screen cable fault tester produced by Shenzhen Noyafa uses the embedded computer for measurement control and data processing. The entire operation is carried out under the Windows interface. The 10-inch touch screen has a large display area, intuitive measurement waveforms, and easy operation and use. Universal USB interface , using the hard disk can store a large amount of measurement data, the measurement results can be stored and printed on-site, and can also be printed off-site, the data will never be lost. Because the embedded computer is used, the reliability of the system is improved, the maintenance is accurate, comparative analysis, the test accuracy is improved, and the error is reduced. Product nickname: comprehensive cable fault tester, buried cable fault tester, power cable fault tester, cable fault detector, high-voltage cable fault tester, cable fault tester The power department of the manufacturer often overhauls the cable, and what should be done when encountering a cable fault What about the correct disposal? Shenzhen Noyafa introduces you to the precise positioning method of the cable: (1) Step-by-step voltage method: The step-by-step voltage method is adopted, which is mainly for the grounding fault of the outer sheath that requires the insulation of the outer sheath of the cable. fault, the step voltage legal point can also be used.
Acoustic measurement method is a high-voltage pulse generator that discharges the faulty cable, the fault point generates arc, and produces a discharge sound. In the case of direct burial of the cable, seismic waves are generated. Headphone or meter output. (2) Acoustic measurement method overview of the method for precise location of cable faults: The use of acoustic measurement method is a method that has been widely used in cable fault location from the past to the present. (3) Acoustic and magnetic synchronization method: It is a comprehensive application of the acoustic measurement method and the electromagnetic wave method. For example, the DTC series of acousto-magnetic synchronous fixed-point instrument adopts the principle of combining the acoustic measurement method with the acousto-magnetic synchronous fixed-point method. (4) Electromagnetic method and audio frequency method outlined in the method of precise location of cable fault: using electromagnetic wave to determine the point or adopting audio frequency legal point, that is, using the change of electromagnetic wave signal or audio signal before and after the cable fault to determine the fault point, in principle, it is OK.
Shenzhen Noyafa is a source enterprise specializing in the production of power testing equipment. It is a manufacturer of insulation resistance testers, grounding resistance testers, cable fault testers, etc. The company has won unanimous praise from the market and customers with its good credit and high-quality products.
