Multi-pulse Cable Fault Testing Machine Overview The HZ-A30 multi-pulse cable fault tester is a high-performance device that integrates a complete set of cable fault testing functions. Developed independently based on the characteristics of the cable fault testing industry, it closely.
The HZ-A30 multipulse cable fault tester is a high-performance device that integrates a complete set of cable fault testing functions. it closely follows the development direction of the international power industry while catering to the rapid growth of the domestic power sector, offering exceptional stability.
The system integrates wireless communication technology, photoelectric knob mouse technology, and expandable Bluetooth technology, significantly enhancing the instrument's functionality and value. These features also greatly improve on-site operation convenience and serviceability.
| Main Unit | Display & Interface: Features a 12.1-inch high-brightness LCD screen with knob mouse control, designed for outdoor field use. Powered by a lithium battery for convenient on-site testing. The engineering plastic case is shockproof, moisture-proof, and highly stable. |
| Connectivity & Sampling: | Equipped with a Wi-Fi module and SIM interface for wireless remote data transmission and mobile terminal technical support. Integrated communication technology ensures stable signal acquisition. The main unit automatically selects from eight sampling frequencies ranging from 3.125 MHz to 400 MHz, with adaptive pulse width to meet testing requirements for cables of varying lengths. |
| Waveform Analysis: | The software automatically identifies and searches for inflection points in three test waveforms: low-voltage pulse method, impulse current method, and multiple pulse method. Fault waveform inflection points are automatically locked, and the fault distance is automatically read and displayed. |
| Waveform Display & Processing: | Waveforms are displayed in three areas on the same screen, with up to ten measured waveforms randomly displayed for selection. Supports both automatic and manual waveform card verification, with functions for storing, replaying, and analyzing test waveform data. |
| Multi-Pulse Generator: |
The unique multi-pulse generator design generates ten low-voltage short-circuit pulse waveforms in a single discharge, automatically optimizing the standard waveform and significantly reducing interference from large oscillations. Pinpointing Instrument |
| Noise Filtering & Path Detection: |
Utilizes dual-selection technology with noise filtering, directly displaying the distance variation between the test point and fault point digitally, while simultaneously detecting cable path direction. Bluetooth Connectivity: Supports mobile phone app connectivity. Via Bluetooth, the mobile phone and headset connect to enable two-person simultaneous pinpointing using a single probe. |
| Remote Assistance & Training | Supports remote expert assistance for waveform analysis, case sharing, teaching and training, and simulated exams, accessible anytime, anywhere. |
