The cable fault pre locator XHGG502A adopts an industrial-grade 10.1-inch touch-integrated computer, a simple operating software interface, industrial-grade integrated circuits and devices, and a built-in large-capacity lithium-ion battery, which is stable, reliable, and easy to use.
This cable fault tester is a special instrument for measuring and analyzing the status and fault distance of power cables. It uses a combination of modern electronic technology and computer technology to achieve signal filtering, acquisition, data processing, graphic display, and graphic analysis. Cable speed measurement, cable length test, cable fault distance test.
This TDR is suitable for low-resistance, short-circuit, open-circuit and disconnection faults of power cables, high-frequency coaxial cables, street light cables, and buried wires made of various materials with different cross-sections and media, as well as high-resistance leakage and high-resistance flashover. Network failure. The technical parameters comply with "GB/T 18268.1 Anti-interference requirements for test equipment used in industrial sites", "DL ∕ T 849.1-2019 General technical conditions for special testers for power equipment Part 1: Cable fault flash tester", "JJF1042-2020" "Calibration Specifications for Cable Fault Testers" standard requirements.
Work mode: TDR(low voltage pulse), ICE(Impulse current), ARM(Arc reflection method) with coupler configured.
Features
• 10.1-inch full-color TFT touch display;
• Embedded system, safe, stable and simple display and operation mode;
• With the function of testing cable wave speed, cable length and fault distance;
• Fully automatic continuous sampling, waveform capture at all times, timely and accurate.
• Equipped with automatic test range setting, automatic waveform analysis and display of test distance.
• Full English menu, two operation methods of touch and coded buttons, simple, fast and reliable.
• Equipped with testing technology of low-voltage pulse method, high-voltage flashover method, and multiple pulse method (8 times), the waveform display is smooth and easy to interpret.
• When using the multiple pulse method, it is used with a pulse coupler to display 8 groups of high and low voltage waveform comparisons, which is convenient for automatic distance testing, manual analysis and distance measurement.
• The instrument has powerful data processing capabilities, making it convenient for users to manage and archive waveform files.
• Has a massive test waveform storage function: the waveforms tested on site can be conveniently stored in the instrument in the order specified by Chinese naming for recall and observation at any time; it can store more than 8,000 records of low-voltage pulses and high-voltage flashover waveforms, and multiple pulses More than 250 waveform records can be recorded, and waveform files can be imported into computer software for management and analysis using USB communication.
• Ultra-high brightness, LED backlight brightness reaches 280nit, resolution 1024*600, convenient for environments exposed to direct sunlight in operation.

Test interface display
Whether you are using the low voltage pulse method, the high voltage flashover method (ICE), or the multiple pulse method (ARC), you must check the following three parameter settings after connecting the cables. (i.e. setting the test mode, selecting the cable medium, and selecting the cable length to be tested)
You can choose different medium
You can choose from different cable lengths
