Author: Noyafa–Cable Tester Suppliers

The high-voltage cable fault tester is a comprehensive set of cable fault detection instruments. It can test the high resistance flashover fault of the cable, high and low resistance grounding, short circuit and cable disconnection, poor contact and other faults. If equipped with an acoustic measuring method, the exact location of the fault point can be accurately determined. It is especially suitable for testing power cables and communication cables of various types and voltage levels.

1. Fully functional, testing is failsafe, fast and accurate. The instrument adopts low-voltage pulse method and high-voltage flashover method for detection, which can test various faults of cables, especially the flashover and high-resistance faults of cables can be directly tested without burning through. If equipped with an acoustic measuring point instrument, the exact location of the fault can be accurately determined.

2. The test accuracy is high, the instrument adopts high-speed data sampling technology, and the A/D sampling speed is 100MHz, so that the instrument reading resolution is 1m, and the detection blind area is 1m. 3. The degree of intelligence is high, and the test results are automatically displayed on the large-screen LCD screen in the form of waveforms and data, and the fault diagnosis is intuitive. And equipped with full Chinese menu display operation function, no need for special training for operators.

4. It has waveform and parameter storage and recall functions, and adopts non-volatile devices, so the waveform and data are not easily lost after shutdown. 5. With double trace display function, the test waveform of the faulty cable can be compared with the normal waveform, which is conducive to further judgment of the fault. 6. With the function of waveform expansion ratio, changing the waveform ratio can expand the waveform for accurate testing.

7. The position of the double cursor can be changed arbitrarily, and the direct distance or relative distance between the fault point and the test point can be directly displayed. 8. It has the function of modifying the propagation speed at any time according to different cables under test. 9. Small size and portable shape, built-in rechargeable battery power supply, easy to carry and use.
