It is a comprehensive diagnostic system designed to perform high-precision cable status analysis, rough fault distance measurement (up to 120km), precise fault pinpointing within 0.1m, and target cable identification (live or dead) to ensure the peak reliability of power distribution networks.
It utilizes advanced 8-Pulse (ARC) Technology combined with High-Voltage Flashover Methods. By employing high-speed 400MHz sampling, it captures and analyzes clear fault waveforms to verify distance. For final pinpointing, it uses Acoustic-Magnetic Synchronization to locate the exact spot of insulation failures within 0.1m.
It minimizes costly downtime by allowing rapid restoration of service. By precisely locating faults (within 0.1m) without extensive excavation, and accurately identifying live cables, it prevents significant economic revenue loss and ensures the absolute safety of maintenance personnel.
Absolutely. It features a massive 10.1-inch industrial touchscreen with an intuitive interface. With “Auto-Ranging” and “Automatic Waveform Analysis” capabilities, it simplifies complex 8-pulse signals into clear, easy-to-read graphs, allowing even less experienced operators to pinpoint faults accurately.
