cable fault tester

Functional characteristics
1. Used to test various types of 380 v. 600 v, 10 kv35kv, 110 kv220kv. 380 kv voltage grade of copper aluminum core power cable, coaxial communication cable and all kinds of local cable fault, Such as cable full length, litar terbuka, short circuit, broken line, low resistance fault, high resistance fault, high resistance leakage, high and low impedance grounding, grounding fault, armor grounding fault, flashover discharge fault, poor grounding contact and cable path identification detection functions;
2. Can cooperate with high-voltage equipment to realize the traditional cable fault test of low-voltage pulse method, impact flashover method, three pulse method, multiple pulse method, speed measurement method.
3. All Chinese operation software and user interface, sub-menu and text prompts to achieve human-machine interaction
4. It should be used as a high-voltage pulse power source for the precise fixed-point instrument of acoustic and magnetic synchronization method and step voltage method.
5. The pulse capacitor should be a combined structure with a convertible capacity.
6, there should be DC output, single discharge, periodic discharge three high-voltage output modes.
7. The discharge device should be built-in and controlled by the relay, and the time interval of periodic discharge can be adjusted by the time relay on the operation panel.
8. With fault conversion function. By means of DC or pulse, the high resistance fault can be converted into a fault with relatively low fault resistance, and the resistance value of the gold attribute dead ground fault can be appropriately improved to facilitate the fault ranging and accurate fixed point.
9. The high-voltage test line should have only one coaxial cable, which can simplify the test wiring, reduce the difficulty of fault detection, and greatly improve the speed and success rate of fault detection.
10 In order to ensure the safety of equipment and human body, there should be grounding resistance detection and grounding protection functions. When the system is poorly grounded, the high voltage cannot be started. When the system is abnormal, the “emergency stop” button on the operation panel can quickly cut off the height
Voltage output and safe grounding.
11. Global waveform and local waveform synchronous display, easy to overall analysis and detail adjustment.
12. Any high-resistance fault presents the simplest waveform characteristics similar to low-voltage pulse short circuit fault, which is easy to interpret.
13, when using multiple pulse method test, the interface collects 8 real waveforms at the same time, which is easier to interpret and reduce test errors, and improve test accuracy.
14. Built-in power supply, can be used for a long time in the environment without power supply.
15. Saiz kecil, ringan, mudah untuk digunakan, high failure detection success rate and test accuracy.
16. Stable performance in any environment, does not crash, signal acquisition high-voltage protection measures are safe
17. Built-in storage/retrieval function, which can easily save or retrieve data and waveform for re-analysis.
18. The test signal provides a variety of pulse width, no test blind area.
