Do you know the principle and characteristics of the high-voltage cable fault tester? The principle of the high-voltage cable fault tester? The high-voltage cable fault tester is a comprehensive set of cable fault detection instruments. Can the high resistance flashover fault of the cable, high and low resistance grounding, short circuit do you know the principle and characteristics of the high voltage cable fault tester? The principle of the high voltage cable fault tester instrument. It can test the high-resistance flashover fault of the cable, the grounding of high and low resistance, short circuit and cable disconnection, poor contact and other faults. If equipped with an acoustic measuring method, the precise 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. For the high-voltage cable fault tester, the smoothness of wired communication and the transmission of power depend on the normal operation of the cable line. Once the line is blocked, it will cause the communication to find out the fault in time and eliminate it quickly, which will cause great economic loss and bad social impact.
Therefore, 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 and devices, adopts computer technology and special electronic technology, and combines the company's long-term successful experience in developing cable testers. High-tech, intelligent A fully functional new product. Let's take a look at the characteristics of the high-voltage cable fault tester. 1. The functions are complete, and the test fault is safe, 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 a sound measuring point instrument, the precise 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, the test results are automatically displayed on the large-screen LCD screen with 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. With waveform and parameter storage and recall functions, non-volatile devices are used, and 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. Do you know the principle and characteristics of the high-voltage cable fault tester? The principle of the high-voltage cable fault tester Shenzhen Noyafa Electronic Technology Co., Ltd.
