Reference Standard: DL / T 849.1-2004 Introduction DBM-2000 cable fault tester is used to measure a host of cable fault nature of the failure, a total length of the cable under test and the approximate location of the cable fault test side pitch. Can be directly connected to a laptop, easy to manage and operate a variety of aluminum foil is widely used in 35KV following different sections, copper power cables, high frequency coaxial cable and telephone cable of low resistance, short circuit, open circuit fault detection is to protect secure supply of the necessary equipment and cable production, maintenance assistant workers. Product Features 1. 35KV following levels can be measured in the low resistance of all cable faults, wide adaptation. 2. The software has a user-friendly and full Chinese menu. Key definitions straightforward. Measuring method is simple and fast. 3. The success rate of fault detection, test accuracy and test convenience better than any kind of domestic detection equipment. 4.8-inch color LCD touch screen as a display terminal, the instrument has a powerful data processing capability and friendly display interface. 5. Samples with very high pressure safety protection measures. Test instruments will not crash and impact damage in high-pressure environments. 6. With a computer communication interface, data and graphics can be easily stored in the computer. 7. No test blind. 8. Built-in power supply, no power in the open environment to test cables and low resistance short circuit faults. Technical Specifications 1. Test method: low-voltage pulse, high pressure flashover law; 2. The impact of high pressure: less than 35KV power cable; 3. Data sampling rate: 100MHz, 50 MHz, 25MHz, 12.5 MHz; 4. Test distance:> 30Km; 5. Reading resolution: less than 1m; 6. System Test Accuracy: less than 50cm; 7. Test cable width is provided: "0.05", "0.1", "0.2", "0.5", "1", "2", "8" microsecond; 8. With a test waveform storage function: to be able to field test waveforms in a predetermined order conveniently stored in the instrument at any time call for observation. You can store large amounts of on-site test waveforms; 9. Total length of the fault waveform can open waveform measured simultaneously with good phase contrast with the screen display and overlay contrast on the screen, you can automatically determine the fault distance; 10. Built-in Power: The instrument is fully charged can work more than three hours in a row, also an external AC power supply; 11. Working conditions: temperature -10 ℃ ~ + 45 ℃, relative humidity of 90%. 12. Weight: 2 kg;
