2. XHGG502A2 — TDR Cable Fault Pre-Locator

High-Resolution Fault Ranging for Rapid Pre-Location

Professional Time Domain Reflectometer for initial fault distance measurement on 400 V to 11 kV cables. Using traveling wave reflection principles, it rapidly measures all types of cable main insulation faults — low-resistance, short-circuit, open-circuit, high-resistance leakage, and flashover — across multiple selectable test ranges. The embedded controller provides automatic waveform capture, fault distance calculation, and data storage. Operates on an independent isolated power supply to prevent interference during impulse discharge from the surge generator, ensuring clean, reliable waveform acquisition in the field.

3. XHDD503C — Cable Fault Pinpointer

Acoustic-Magnetic Synchronization — 0.1 m Precision

Professional digital pinpointer using acoustic-magnetic synchronization for precise fault localization. When the surge generator applies HV impulses, acoustic and electromagnetic signals propagate from the fault point. The pinpointer captures both via its IP65-rated intelligent metal probe, calculates the time difference in real time, and displays synchronized waveforms on the 5-inch TFT ultra-bright 800×480 true-color display. Operates in four modes (Standard, Enhanced, Noise Reduction, Custom) with 120 dB fully automatic/manual gain, 16-gear dynamic range, and 600 Ω military-grade noise-reduction headphones for operation in the harshest acoustic environments. Weighs just 2 kg total (host 0.6 kg + sensor 1.4 kg).

System Function & Workflow

Fault Conditioning & Flashover (XHHV535-2L)Use DC or high-voltage pulse to make the cable fault point flash over and discharge, creating a detectable transient signal at the fault location for measurement and pinpointing.
Fault Pre-Location (XHGG502A2)Apply the traveling wave reflection principle to make a rough measurement of all types of cable main insulation faults. The TDR captures returning pulses and calculates the fault distance within seconds across multiple selectable test ranges.
Route Tracing & Cable Identification (XHGX507C)Deploy the path comprehensive tester to trace the exact cable route, measure burial depth, and positively identify the target cable among multiple underground circuits.
Surge Impulse Generation (XHHV535-2L)Apply periodic high-voltage surges (~6 s automatic cycle) to create consistent acoustic and electromagnetic transient signals at the fault point for precise localization.
Precise Pinpointing (XHDD503C)Walk the cable route with the acoustic-magnetic pinpointer using the intelligent time-difference method. Monitor the synchronized waveform display — the point where acoustic-magnetic time delay approaches zero is directly above the fault, within 0.1 m.
Cable Repair & VerificationExcavate precisely at the marked point, repair the cable, and verify service restoration with a final insulation test.

Frequently Asked Questions

Q1: What makes the XHHV535-2L different from standard surge generators?

The XHHV535-2L is the ultra-portable class leader at just ≤30 kg — less than one-quarter the weight of comparable 32 kV units. It achieves this through a single 2 μF capacitor design producing 1024 J of discharge energy, which is optimized for 400 V to 11 kV cable networks. For higher-voltage cables requiring the full 2048 J of larger systems, the XHHV535-4TS series is recommended. For 11 kV and below distribution networks, the 2L provides the ideal balance of portability and diagnostic power, enabling single-technician deployment without lifting equipment.

Q2: What cable types and fault conditions can this system detect?

The system handles all common power cable types (XLPE, PILC, EPR) from 400 V to 11 kV and all fault categories: low-resistance and short-circuit faults (via LV pulse TDR), open-circuit and broken-wire faults (via TDR pulse reflection), and high-resistance leakage and flashover faults (via impulse current/voltage and ARC multi-pulse methods). The 3-step system function — flashover discharge → traveling wave pre-location → acoustic-magnetic pinpointing — provides a complete diagnostic workflow for any cable main insulation fault.

Q3: Can this system truly be operated by one technician?

Yes, this is one of the key design goals of the 535-2L system. The surge generator weighs ≤30 kg and can be carried by one person. The TDR pre-locator operates on an independent isolated supply. The pinpointer weighs only 2 kg total and runs >8 hours on 4×18650 batteries. The path tester is a handheld receiver with intuitive guidance. For safety during high-voltage operations, standard utility protocols recommend a two-person team, but all individual instruments are single-operator capable.

Q4: What is included in a standard system purchase?

Each system includes all four core instruments, test cables, connection adapters, chargers, headphones, and comprehensive user manuals. The XHDD503C pinpointer includes the 600 Ω military-grade noise-reduction headphone set. The XHGX507C path tester includes the built-in receiving coil and flexible caliper; the A-frame for step-voltage fault finding is available as an optional accessory. All components ship in reinforced wooden cases for international transit.

Q5: What are the delivery, warranty, and supply terms?

Standard delivery time is 5–8 working days. Each system is packaged in reinforced export-grade wooden cases with foam cushioning. XZH TEST provides standard manufacturer warranty with optional extended coverage. Minimum order quantity is 1 set, with T/T payment terms. Annual supply capacity is 500 sets, ensuring availability for both trial purchases and fleet procurement.
