Product Features
✅ Three-Level Pulse Ranging for Accurate Fault Detection
The FB47 uses an advanced three-pulse method to automatically determine fault distance with clear waveform display. This technology is especially effective for high-resistance and flashover faults, which are often difficult to locate with conventional testers. The system provides a measurement range of over 64 km with 0.1 m accuracy, ensuring precise fault localization and reducing time spent on troubleshooting.
✅ Acoustic-Magnetic Synchronous Pinpointing with Noise Reduction
Equipped with BNR noise reduction and digital filtering, the FB47 excels in noisy environments. The acoustic-magnetic synchronous locator features directional indicators and distance display, allowing operators to accurately pinpoint faults even amid strong interference. This results in faster, more reliable fault identification without false signals.
✅ Built-in Lithium Battery for Grid-Independent Operation
Designed for field use where external power may not be available, the FB47 includes a high-capacity lithium battery that supports full operation without grid connection. This enhances mobility and ensures uninterrupted testing in remote locations, railways, tunnels, and outdoor substations.
✅ All-in-One Integrated Design with High-Voltage Generator
Unlike separate devices, the FB47 combines ranging, path tracing, pinpointing, and a high-voltage signal generator in one trolley-mounted system. The HV generator offers DC, single pulse, and periodic pulse modes up to 32 KV, with safe insulation and easy wiring. This integration streamlines workflow and improves onsite safety.
✅ User-Friendly Operation with Voice Guidance & Insulated Safety Design
Featuring voice prompts and one-touch controls, the FB47 minimizes training time and operational errors. Its fully insulated structure and auto-protection mechanisms ensure operator safety during high-voltage testing.
