Cable Fault Detection Instrument

 



The smooth operation of wired communication and power transmission depends on the normal operation of cable lines. Once a line fault occurs, it will cause communication failures and power outages. If the fault is not detected and repaired promptly, it will result in significant economic losses and adverse social impacts. Therefore, the GH-2136 Cable Fault Tester is an essential tool for maintaining various cables. The intelligent cable fault tester adopts multiple fault detection methods, utilizes the latest electronic technology achievements and components, incorporates computer technology and special electronic technology, and combines our company's long-term experience in developing cable testers to launch a high-tech, intelligent, and fully functional new product.

Product Aliases:



Cable fault tester, cable fault detection instrument, high-voltage cable fault tester, cable fault tester, cable fault tester



Product Features:



●  Full-featured, safe, rapid, and accurate fault testing. The instrument uses the low-voltage pulse method and high-voltage flashover method for detection, capable of testing various cable faults. For power cable flashover and high-resistance faults, direct testing is possible without burning through. If equipped with an acoustic point locator, the exact fault location can be accurately determined.



●  High testing accuracy. The instrument adopts high-speed data sampling technology with a reading resolution of 1m. High intelligence. Test results are automatically displayed on the large LCD screen in small text and data, making fault judgment intuitive. It also features menu-driven operation, requiring no special training for operators.



●  Waveform and parameter storage and recall functions. Non-volatile devices ensure waveforms and data are not lost after power-off.



●  Dual-trace display function. Allows comparison of the faulty cable's test waveform with a normal waveform, aiding further fault diagnosis.



●  Waveform expansion ratio function. By changing the waveform scale, the waveform can be expanded for precise testing.



●  Controlled measurement cursor, automatically searches along the line and stops at the inflection point of the fault waveform.



●  Arbitrary positioning of dual cursors to directly display the direct or relative distance between the fault point and the test point.



●  Printing function. Test results can be printed and archived.
