Pro Underground Cable Fault Pinpointer XHGX507

The XHGX507 Pro Underground Cable Fault Pinpointer is a professional-grade electromagnetic induction detection system engineered for precise underground cable fault location. It excels at pinpointing cable-to-ground insulation faults up to 2MΩ using advanced step voltage detection technology, eliminating the need for high-voltage flashover equipment. Designed for street lighting cables, buried power distribution cables, and communication cable networks.

Key Features

Step Voltage A-Frame Fault Detection: Proprietary step voltage detection method pinpoints cable-to-ground insulation faults up to 2MΩ without high-voltage equipment. The A-frame accessory measures potential differences along the cable path to locate the exact fault point with zero potential crossing detection

2MΩ High-Resistance Fault Capability: Uniquely designed to locate high-resistance cable insulation failures that traditional time-domain reflectometry (TDR) and high-voltage surge methods struggle with. Ideal for single-phase metallic ground faults where discharge energy is insufficient for acoustic pinpointing

All-Digital LCD Display System: Large backlit LCD screen displays real-time signal strength ladder diagram (0-999), numeric value, gain level (0-100dB), frequency mode, battery status, and depth/current measurements. Voice FM tone prompt reduces operator eye fatigue during extended field work

Dual-Frequency Transmitter: Low Frequency (LF) for long-distance tracking up to 15km with minimal adjacent line interference, and Radio Frequency (RF) for high-resistance pipelines and poor grounding conditions with automatic impedance matching (5Ω-3000Ω)

Three Signal Application Methods: Direct connection for strongest signal and optimal accuracy; Coupling clamp for live (charged) cable detection without service interruption; Built-in induction antenna for areas where cable access is physically limited

Three Receiver Working Modes: Peak method for fast cable tracking, Trough method for precision positioning in low-interference environments, and Step Voltage method with A-frame for fault pinpointing

50Hz Passive Detection: Locate energized power cables by detecting their natural 50Hz frequency emission — no transmitter connection required, ideal for pre-excavation utility surveys

Depth and Current Measurement: Direct-reading digital depth display (up to 10m), plus 45-degree and 80% verification methods. Real-time current measurement distinguishes target cable from parallel adjacent pipelines even at different burial depths

Built-in Ohmmeter: Automatic loop resistance measurement and continuous auto-output impedance matching ensures optimal signal transmission regardless of soil conditions or cable type

Portable Field-Ready Design: Receiver 70cm × 20cm × 11cm (3kg), Transmitter 16cm × 16cm × 39cm (4kg). Both powered by rechargeable 7.4V lithium batteries. LCD backlight for night operation. Operating temperature range -10°C to +55°C
