Product Description

Entry-Level TDR — High Value, No Compromise on Essentials. The XHGG501D delivers professional cable fault distance measurement, wave velocity testing, and resistance measurement at a price point accessible to smaller utility teams, electrical contractors, and maintenance departments building their first cable diagnostic capability.

The XHGG501D Cable Fault Tester is a microcontroller-controlled instrument designed for measuring and analyzing fault status and distance on low-voltage and medium-voltage power cables. Built around a 10-inch industrial LCD with touch operation, it implements the traveling wave method principle — injecting low-voltage pulses (35V, 0.2μs/2μs) into the cable under test and analyzing the reflected waveform for fault distance calculation. For high-resistance faults, it supports the high-voltage flashover method, capturing transient discharge reflections via external sampler. The instrument also performs cable wave velocity calibration and fault resistance measurement, covering the complete diagnostic workflow from fault classification to rough pre-location.

What the XHGG501D does not do is multi-pulse ARC testing — that capability is reserved for the higher-tier XHGG502 and XHGG502A models. For field teams whose fault profile consists primarily of low-resistance shorts, open circuits, and occasional high-resistance flashover faults, the XHGG501D provides everything needed without paying for capabilities that will rarely be used.

Why the XHGG501D — The Practical Choice

10-inch Industrial LCD with Touch Control: Large, clear display for waveform analysis. Microcontroller centralized architecture with touch-based operation and strong anti-interference capability — stable performance in electrically noisy substation environments.
Three-in-One Measurement: Fault distance measurement (TDR), wave velocity calibration for each cable type, and fault resistance measurement — the three core diagnostic functions every cable maintenance team needs.
Dual Test Methods: Low-voltage pulse method (35V) for low-resistance, short-circuit, open-circuit, and disconnection faults. High-voltage flashover method for leakage and flashover high-resistance faults — covers the majority of field-encountered fault types.
Automatic Continuous Sampling: Never misses a transient discharge waveform. The instrument captures and displays every reflection event — no manual triggering required.
Built-in 10400mAH Lithium Battery: High-capacity battery supports hours of cable testing without mains power. AC 110V~240V compatible for extended operations and charging.
IP54 Protective Chassis: Dust-protected and splash-proof — survives the cable trench, the substation floor, and the back of a service truck.
-20℃ to +65℃ Wide Temperature Operation: Functions reliably from winter outdoor substation maintenance to summer roadside cable diagnostics — no climate limitations.
Compact & Portable: 358×284×168mm and 4.6kg — easily carried by one technician. The same chassis form factor as the larger XHGG series, with familiar layout for crews upgrading from this entry point.

Frequently Asked Questions

Q: Who is the XHGG501D designed for?

The XHGG501D is purpose-built as an economical entry-level TDR cable fault locator for small to mid-size electrical contractors, property maintenance teams, and training institutions. It delivers essential cable fault pre-location capability at an accessible price point without compromising on industrial build quality and IP54 field protection.

Q: What cable faults can the XHGG501D detect?

Using the low-voltage pulse method, the XHGG501D effectively detects open-circuit, short-circuit, and low-resistance faults in power cables rated 35kV and below, as well as coaxial cables, street light cables, and buried wires. It also supports cable length measurement and wave velocity calibration. For high-resistance and flashover faults, an external HV pulse generator is required for flashover testing.

Q: How does the XHGG501D differ from the XHGG502 series?

The XHGG501D is optimized for straightforward low-voltage pulse testing with a 10-inch touchscreen, 16km range and 1.0m resolution at an economical price. The XHGG502 series adds ARC multi-pulse technology, 400MHz sampling, 0.07m resolution, 60-120km range, and advanced features like handwriting annotation and one-tap reporting. Choose the 501D for routine cable maintenance and the 502 series for professional fault diagnostics across complex cases.

Q: What is the test range and accuracy?

With 100MHz sampling, the XHGG501D achieves a maximum test range of 16km with 1.0m minimum resolution and test blind zone ≤10m. It provides 8 selectable pulse widths from 0.1μs to 10μs and 7 preset test ranges, making it suitable for most common low-voltage and medium-voltage cable maintenance applications.

Q: Is the XHGG501D suitable for outdoor field use?

Yes. The IP54-rated chassis protects against dust and water splashes, and the 10-inch industrial touch LCD with strong anti-interference design operates reliably in outdoor environments. The microcontroller-based system is stable, energy-efficient, and designed for routine field service conditions encountered by maintenance crews.

Q: What warranty and after-sales support is included?

Standard warranty is 12 months from delivery covering product quality defects, with lifetime maintenance and technical support. A detailed user manual is included with each unit. Extended warranty options and on-site training services are available upon request. Most technical inquiries receive a response within 24 hours.

Absolute workhorse for our utility crew，I’ve used this cable fault tester on underground power lines across Ohio suburbs for four months straight. Last Tuesday, we located a water-soaked cable short under a residential driveway in Columbus; it pinpointed the fault within 3 feet. It blocks signal interference perfectly amid dense parallel power lines in neighborhood subdivisions. The heavy-duty shell survives bouncing around our work trucks, and the battery stays charged through full field shifts. It slashes our digging hours and never fails on emergency service calls.

The XHDD503C is hands down the best fault locator we’ve used in Austin, Texas. It’s shockingly precise on commercial lot faults, super durable for daily field work and drastically cuts our excavation headaches. Worth every penny for our utility crew.

We purchased the XHGG502A for our company's cable fault detection work, and we are extremely satisfied with its overall performance! The equipment is stable and reliable, and the measurement data is accurate. Compared to similar products we used before, it has stronger resistance to moisture and dust, making it suitable for various harsh working environments. Furthermore, its compact size makes it easy to store and transport. The technical team at Xuzhihui Electromechanical also provides regular follow-up visits and maintenance advice, which gives us great confidence in the product and service!
