Cable Fault Locator is mainly developed by our company for accurate cable fault point location. It has high anti-interference and high sensitivity. This instrument combines low-noise design with high-performance digital filters, using FIR filters, and integrates multiple working modes such as acoustic-magnetic synchronous point location and step voltage, providing more ways for accurate cable fault point location. With a 4.3-inch high-brightness OLED color LCD, it is clearly visible outdoors. The intuitive and simple graphical display and one-key operation mode allow accurate and rapid point location of various cable faults.
[Functional Features]
1. The data display part uses a high-brightness 4.3-inch OLED color LCD, making the display interface clearer.
2. The function and parameter adjustment part uses a one-key programmable pulse encoding keyboard, making the operation panel more concise and operation more convenient.
3. This instrument collects and displays the waveform of the audio part in real time. By observing the repetitive waveform characteristics and the distance axis, the distance to the fault point can be roughly observed, and the operator is less prone to fatigue when observing waveforms.
4. In the acoustic-magnetic point location mode, there are single and continuous modes. If the discharge frequency is too fast and the gap time is too short, the user can select the single mode to carefully analyze the waveform and related data of one discharge, and waveform page turning is supported in single mode.
5. Four filter frequency bands are used in acoustic signal acquisition: low frequency band, medium frequency band, high frequency band, and full frequency band. Users can choose according to the actual situation on site.
6. The step voltage part uses waveform display and continuously samples and refreshes the signal, enhancing the user's analysis of signal continuity and resolution of sudden jump signals.
7. The step voltage part has multiple gear subdivisions. During adjustment, large signals are automatically attenuated to ensure that when the maximum voltage amplitude within the test range is input, the displayed signal is not clipped.
8. The audio part filtering uses FIR digital filtering technology, making the characteristic frequency bands more obvious and the filtering performance better.
9. The distance to the fault point can be displayed within the range of 0-25m.
10. In continuous mode, compressed waveforms within 15m distance can be displayed; in single mode, waveforms within 15m distance can be expanded for analysis.
