ARC Cable Fault Locator 120km Automatic Waveform Analysis 8-Group Multi-Pulse XHGG502A

The XHGG502A ARC Cable Fault Locator combines a 120km test range with automatic waveform analysis to dramatically simplify the cable fault diagnosis workflow. Built around a 10.1-inch industrial touch-integrated computer with embedded system architecture, it covers the full spectrum of cable fault types — low-resistance short circuits, open circuits, high-resistance leakage, and flashover faults — on power cables, high-frequency coaxial cables, street light cables, and buried wires across all materials, cross-sections, and dielectric media.

What distinguishes this instrument is its dual-mode operation: operators can rely on the fully automatic fault analysis system that handles range setting, waveform capture, and distance calculation with a single setup, or switch to manual waveform analysis for expert-level interpretation on complex fault signatures. The 8-group multi-pulse ARC comparison display provides side-by-side high-voltage and low-voltage waveform views, making fault distance determination unambiguous even for less experienced field technicians.

• Auto-Ranging: The instrument automatically selects the optimal test range from 10 preset options (100m to 100km) based on cable type and length — no manual configuration required.
• Auto Waveform Capture: Fully automatic continuous sampling ensures no transient discharge event is missed. The system captures and freezes the clearest waveform automatically.
• Auto Distance Calculation: Built-in waveform analysis algorithm identifies the fault reflection signature and displays the fault distance in meters. Operators get a result without interpreting raw waveforms.
• One-Touch Operation: Full English menu with both touchscreen and coded push-button input. Simple, fast, and reliable — designed for high-volume field testing environments where speed matters.

• 120km Maximum Range: Industry-leading detection distance for long-haul power transmission cables and telecom trunk lines.
• 400MHz Sampling, 0.07m Resolution: Ultra-high-speed variable sampling captures the finest waveform detail for pinpoint-accurate distance measurement — over 7* finer than conventional 100MHz instruments.
• 8-Group ARC Multi-Pulse Comparison: When used with a pulse coupler (DC 35kV), the instrument simultaneously displays 8 groups of high-voltage and low-voltage contrast waveforms. This direct visual comparison eliminates the guesswork that plagues single-trace fault interpretation.
• 300Vpp Low-Voltage Pulse, 8 Selectable Widths: From 0.15μs for short-range precision to 10μs for maximum penetration on long cables — match the pulse to the application for the cleanest reflection trace.
• Three-in-One Test Modes: TDR (low-voltage pulse for low-resistance/open-circuit faults), ICE (impulse current for high-resistance flashover), and ARM (arc reflection multi-pulse for complex high-impedance faults).
• Massive Onboard Storage: 8,000+ waveform records stored locally with Chinese/English naming. Export via USB to PC software for archival management, comparative analysis, and report generation.
• 10.1-inch Industrial Display: 1024*600 resolution with high-brightness LED backlight. Clear visibility in direct sunlight and dusty field conditions. Embedded system with industrial-grade integrated circuits for long-term reliability.
• Comprehensive Cable Coverage: Power cables (LV/MV/HV), high-frequency coaxial, street light, traffic signal, telecom local loop, and buried wires of all cross-sections and media types.
