Product Description

Multiple Pulse Cable Fault Tester

Darui Electric recommends for you:

Product Features:

The multiple pulse cable fault tester complete set consists of the cable fault tester main unit, cable fault testing accessories (path finder and fault locator), and cable testing high voltage unit. It is simple and convenient to test.

1. The instrument adopts an industrial embedded computer platform system, a full computer XP system operation platform, integrated software testing, and is equipped with cable fault testing software.

2. It adopts a 12.1in large screen touch system, with dual control of touch pen and touch mouse, high-brightness display, suitable for outdoor sunlight use, lithium battery power supply, convenient for on-site testing. The engineering aluminum alloy chassis is shockproof and moisture-proof, achieving extremely strong stability.

3. It adopts USB communication interface, stable signal acquisition. The main unit can automatically select five sampling frequencies from a minimum of 6.25MHz to a maximum of 100MHz, adaptive pulse width, meeting the testing requirements of different lengths of cables, reducing rough measurement errors and improving testing accuracy.

4. The software realizes fully automatic identification and search for low-voltage pulse and multiple pulse methods, automatic positioning of waveform fault inflection points, automatic reading and display of fault distance by the instrument, simultaneous three-zone waveform display, simultaneous random display of ten low-voltage pulse waveforms for selection, and realizes both automatic and manual processing modes, enabling dual positioning operations on the waveform. The dual cursor movement can reach 0.15 meters, improving rough measurement accuracy and reducing waveform errors.

5. The unique multiple pulse generator design allows three testing methods to be completed without rewiring on site, and one discharge can obtain ten low-voltage short-circuit pulse waveforms, greatly reducing large oscillation interference. The multiple pulse generator is small in size, weighing only 5KG, truly achieving lightweight complete equipment.

6. The multiple pulse cable fault tester main unit supports built-in WiFi reception function. The dedicated 3G software can provide expert remote real-time on-site testing technical services at any time. Experts can remotely control the user's main unit, and the business technology is equipped with an Android version testing software for mobile phones, providing users with timely and accurate waveform analysis and communication guidance anytime and anywhere, making your work worry-free (optional).

7. Built-in on-site waveforms and on-site physical wiring diagrams facilitate on-site testing comparison and daily learning, and can automatically generate test reports and print them.

8. The key fault locator part can directly digitally display the distance from the tester to the fault point. It adopts noise suppression technology, which is another innovation in domestic similar positioning technology, providing strong guarantee for quickly and accurately finding cable faults and reducing power outage losses.

9. Two options are available for the high-voltage discharge part. The new 8.4kg high-frequency high-voltage power supply replaces the 65kg test transformer and operation box, with wide applicability and truly comprehensive lightweight.
