High voltage cable fault tester

Cable faults are very serious losses for today's rapidly developing society, as our demand for power and communication equipment is increasing and we have gradually become accustomed to their existence. If a cable fault occurs, it will cause huge social and economic losses. Therefore, cable fault detectors are very valuable, as they can detect where the cable is faulty in a timely manner and reduce losses.

High voltage cable fault testerComposed of a laptop, testing system, path signal generator, path signal receiver, and positioning instrument, it can complete two tasks: cable fault testing and cable data management.

DGC-711ZHigh voltage cable fault testerThe microprocessor completes the process of converting signals into digital signals, including acquisition, storage, digital filtering, cursor movement, distance calculation, waveform comparison, waveform expansion, etc., until the display is sent to the LCD display. Communication ports can also be used to communicate with PCs for feedback, detection, and signal processing results.

Performance characteristics:

1. This product is used for rapid and accurate detection of buried fault points, as well as cable burial paths and depths.

2. The use of special structured acoustic vibration sensors and low-noise devices as preamplifiers greatly improves the sensitivity of instrument positioning and path detection. In signal processing technology, the digital display of the distance between the fault point and the sensing probe eliminates the blindness of fixed-point positioning.

3. When a faulty cable is overhead in a cable trench, the vibration sound of the entire cable makes it impossible for any fixed-point instrument to determine the specific location of the closed fault. Nowadays, as long as the sensor probe of this instrument is in contact with the faulty cable or nearby cable, the fault distance can be displayed, making it effortless to quickly determine the fault location.

4. The theory of power frequency adaptive cancellation and high power frequency notch technology greatly enhance the anti-interference ability of power frequency signals in strong power frequency electric field environments, and reduce fixed-point blind spots. In terms of instrument functionality, the use of acoustic electric synchronous reception and display technology effectively overcomes the difficulty of fixed-point positioning caused by environmental noise interference in the fixed-point site. Especially the digital display of fault distance eliminates the need for operators to analyze and judge complex waveforms, and to a considerable extent replaces the rough distance measurement function of the flash tester. For hundreds of meters long faulty cables, it is generally not necessary to conduct rough measurements to implement fixed points, which truly achieves high efficiency, speed, and accuracy.

5. The operation is extremely simple, just turn on the power switch, there is no need to shift gears or select functions. Compact, compact, modular, easy to carry and repair, with * functionality.
