Product Description

System Components

1. XHHV535-4Z — 2048J High Voltage Surge Generator

Impulse Energy Source

The powerhouse of the system. Delivers up to 2048 Joules of surge energy at 32kV with multi-level selector for precise energy control. Provides the high-energy impulses required for arc reflection fault pre-location and acoustic-magnetic pinpointing on low and medium voltage cables. Integrated operator safety interlocks ensure safe field operation.

Surge Energy: 2,048 Joules (maximum)

Output Voltage: Up to 32 kV with multi-level surge selector

Safety: Integrated operator safety assurance systems

2. XHGG501B — Digital TDR Cable Fault Pre-Locator

Precision Ranging

High-resolution Time Domain Reflectometer (TDR) for initial fault distance measurement. Supports multiple test methods including low-voltage pulse, high-voltage pulse, and arc reflection modes. Equipped with a large color LCD display and automatic waveform analysis for rapid, accurate pre-location of open circuits, short circuits, and high-resistance faults.

Test Methods: LV pulse, HV pulse, ARC reflection

Display: Large color LCD with waveform storage

Function: Automatic waveform comparison and fault ranging

3. XHDD503C — Acoustic-Magnetic High-Precision Pinpointer

Exact Fault Location

High-sensitivity acoustic-magnetic synchronous receiver for pinpointing fault positions to centimeter-level accuracy. Detects the acoustic vibrations and electromagnetic signals generated by surge impulses at the fault point, providing synchronized dual-channel display for confident fault location even in noisy urban environments. Lightweight handheld receiver with headphone output for hands-free operation.

Detection Method: Dual-channel acoustic-magnetic synchronous

Output: Visual meter + audio via headphones

Accuracy: Centimeter-level fault pinpointing

Complete Fault Location Workflow

Cable Insulation TestPerform initial insulation resistance measurement to confirm fault presence and characterize fault type (high/low resistance).

Fault Pre-Location (XHGG501B)Connect the TDR pre-locator to measure the approximate distance to the fault using LV pulse, HV pulse, or ARC reflection methods.

Route TracingTrace the exact cable path and mark the route on the ground surface to prepare for precise localisation.

Surge Impulse Generation (XHHV535-4Z)Apply high-energy surges to the faulty cable to create detectable acoustic and electromagnetic signals at the fault point.

Precise Pinpointing (XHDD503C)Walk the cable route with the pinpointer to identify the exact fault location to within centimeters — minimizing excavation area.

Cable Repair & VerificationExcavate precisely at the marked point, repair the cable, and verify restoration with a final insulation test.

Applications

Urban Distribution Networks: Fault location on buried low-voltage and medium-voltage distribution cables in city environments — where precise pinpointing minimizes road excavation and traffic disruption.

Industrial Facilities: Diagnostics on plant power distribution cables, including those running under concrete floors, paved yards, and building foundations.

Commercial & Residential Complexes: Underground cable fault detection in apartment blocks, shopping centers, and office parks where access is constrained.

This full‑set cable fault testing system (XHHV535‑4TS, XHGG502A, XHDD503C, XHGX507C) performs brilliantly for our DEWA government team. It quickly located underground cable faults at Al Sheraa headquarters in Al Jaddaf, Dubai. Stable under high heat and sandy conditions, the combined modules deliver precise readings, drastically cutting troubleshooting time. Reliable all‑in‑one solution for urban utility maintenance.
