What are the precise location methods for cable faults? The price of the cable fault precise location tester is the touch screen cable fault tester produced by Shenzhen Noyafa. The host uses an embedded computer for measurement control and data processing. The entire operation is performed under the Windows interface. The 10-inch cable fault precise location method includes: 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, and the measurement waveform is intuitive and easy to operate. , Universal USB interface, the use of 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. The price of the cable fault precise spotting instrument has improved the reliability of the system, accurate comparison and analysis of maintenance, improved test accuracy and reduced errors due to the use of an embedded computer. Product nickname: cable fault comprehensive tester, buried cable fault tester, power cable fault tester, cable fault detector, high-voltage cable fault tester, cable fault tester Manufacturers and electric power departments often repair cables, and cable faults are accurately located. Price How to deal with cable faults correctly? Shenzhen Noyafa introduces you to the precise positioning method of cables: (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-magnetic synchronization method: It is a comprehensive application of the acoustic measurement method and the electromagnetic wave 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 electric power testing equipment. It is an insulation resistance tester manufacturer, a ground resistance tester manufacturer, a cable fault instrument manufacturer, etc. The company wins the market with good credit and high-quality products. And customers alike.
