0.10m ARC Cable Fault Pre-Locator | 65km 10.1-inch IP54 | XHGG501E

The XHGG501E ARC Cable Fault Pre-Locator integrates a 10.1-inch industrial full-color TFT touchscreen with an embedded system, offering stable, intuitive operation in the field. Built with industrial-grade components and a high-capacity 5200mAH lithium battery with fast charging, it performs signal filtering, high-speed acquisition, data processing, and waveform analysis to determine cable wave speed, total length, and fault distance. The instrument detects the full spectrum of cable faults — low-resistance, short-circuit, open-circuit, disconnection, leakage high-resistance, and flashover high-resistance — on power cables, high-frequency coaxial cables, street light cables, and buried wires across all cross-sections and dielectric media. All technical indicators, anti-interference performance, and metrological calibration comply with GB/T 18268.1, DL/T 849.1-2019, and JJF1042-2020 standards.

Unlike instruments that bundle expensive accessories into a mandatory purchase, the XHGG501E ships as a fully-capable standalone unit covering TDR (low-voltage pulse) and impulse high-voltage flashover methods. The DC 35kV pulse coupler and 8-pulse ARC multi-pulse capability are optional — purchase them with the instrument, or add them later when your testing requirements expand. No forced bundle. No wasted budget on features you don't yet need.

• 0.10m Best-in-Class Resolution: 80MHz variable-frequency sampling (80/40/10/2/1MHz) achieves 0.10m minimum resolution — over 5* finer than standard 0.5m instruments at a comparable price point. Identify faults between adjacent cable joints with confidence.
• 10.1-inch 280nit TFT Touch Display: 1024*600 resolution with ultra-bright LED backlight. Full-color capacitive touchscreen remains sharp and operable under direct sunlight. Dual-mode: touch for navigation, coded push-button for gloved-hand control.
• Three Test Modes, Flexible Configuration: LV pulse (100V±15%, 5 selectable widths from 0.125μs to 10.0μs) works standalone. HV flashover method for leakage and flashover faults. 8-pulse ARC multi-pulse — when paired with the optional DC 35kV coupler — simultaneously displays 8 groups of high/low voltage waveform comparisons for unambiguous fault distance determination.
• Fully Automatic Operation: Automatic continuous sampling never misses a transient discharge waveform. Automatic range setting selects from 5 presets (300m/1km/5km/25km/65km). Automatic waveform analysis identifies the fault reflection and displays the distance — no manual cursor placement needed.
• 8,000+ Waveform Storage with USB Export: Massive onboard memory stores over 8,000 LV/HV waveform records and 250+ multi-pulse records. Chinese naming support for organized field archiving. USB interface exports all waveform files to PC software for secondary analysis and formal report generation.
• 2-Hour Fast Charge, 5+ Hour Field Operation: Built-in 5200mAH lithium battery charges from empty to full in approximately 2 hours and sustains over 5 hours of continuous testing. Test open-circuit and low-resistance faults entirely on battery — no mains power, no generator required for these fault types.
• IP54 Rugged Chassis, -20℃~+65℃: Dust-protected and splash-proof protective casing designed for demanding outdoor construction and substation environments. Functions reliably from winter cold to summer heat.
• Embedded System with 8000+ Record Management: Purpose-built embedded architecture — stable, secure, low-power. Powerful data processing system supports classified storage, retrieval, and management of waveform test records at the instrument level.
