The XHGG502 TDR underground cable fault locator features an industrial-grade 12.1-inch touch all-in-one computer with intuitive operating software for efficient human-computer interaction testing. Built with industrial-grade integrated circuits and components, it includes a large-capacity lithium-ion battery for stable, reliable operation.

This specialized instrument measures and analyzes power cable status and fault distance using modern electronic technology combined with computer processing for signal filtering, data acquisition, processing, and graphical display/analysis.

• Detects low-resistance, short-circuit, open-circuit, and disconnection faults in power cables
• Identifies high-resistance leakage and high-resistance flashing network failures
• Works with various cable types including high-frequency coaxial, street light, and buried wires
• Compatible with cables of different sections and media materials

The XHGG502 ARC Cable Fault Pre-Locator accurately detects main insulation failures in power cables up to 35KV, calibrates cable length, and provides rough fault distance measurements using three advanced methods:

• Low-voltage pulse reflection method (TDR)
• High voltage flashover method (DECAY)
• Arc reflection method (ARC single shot and multi-shot)

Low Voltage Pulse Test Mode: (No high voltage pulse generator required)
