Product Description
TDR Cable Fault Pre-Locator with Micro Printer | XHGG501B

XHGG501B

The TDR cable fault pre-locator is a professional diagnostic instrument designed for measuring low resistance, short circuit, open circuit fault, high resistance leakage and high resistance flashover fault conditions in power cables, high frequency coaxial cables, local telephone cables, street lamp wiring and buried conductors across various materials, cross-sections and dielectric media.

Portable TDR Cable Fault Pre Locator Diagnostic Tester with Built-in Micro Printer System | XHGG501B

Key Features
  • SCM operating platform with push-button operation mode and integrated micro-printer, enabling on-demand printing of test waveforms and related content at any time
  • Comprehensive system functions: fault distance measurement, fault location, propagation speed test, fault resistance analysis, cable path tracing, and buried depth detection
  • Multiple test methods: low voltage pulse, flashover method, audio method, acoustic-magnetic synchronization, valley value detection, peak detection, and electromagnetic induction
  • Display control: 5.7-inch industrial LCD flash tester with built-in 24V/7Ah DC power supply providing up to 6 hours of continuous operation; auxiliary pointer table display
  • Test range: maximum distance 60km, detection depth 2-5m
  • Measurement accuracy: rough measurement error ±10m (absolute) or 1% (relative); fine measurement error ±0.2m (fixed point, path, depth)
  • Sampling frequency: 100MHz with minimum resolution of 0.5m (100m/μs)
  • Automatic continuous sampling ensures no discharge waveform is missed
  • Low voltage pulse output: width 0.1μs and 2μs, amplitude 100Vpp
  • Output power: path power 100W, impulse power 0~400W
  • Impact high voltage: 0~35kV

Frequently Asked Questions
Q1: What types of cable faults can this TDR pre-locator detect?

This instrument is capable of detecting a wide range of cable faults including low resistance faults, short circuits, open circuits, high resistance leakage faults, and high resistance flashover faults. It works effectively across power cables, coaxial cables, telephone lines, street lighting circuits, and buried wiring of various cross-sections and dielectric materials.

Q2: What is the maximum test distance and accuracy of this device?

The pre-locator has a maximum test distance of 60km with a detection depth of 2-5 meters. Rough measurement accuracy is ±10m (absolute) or 1% (relative), while fine measurement accuracy reaches ±0.2m for fixed point location, path tracing, and depth measurement.

Q3: How does the integrated micro-printer function work?

The built-in micro-printer is fully integrated into the SCM operating platform. Users can print test waveforms, measurement data, and complete test reports directly from the instrument at any time using the push-button interface, eliminating the need for external printing equipment during field operations.

Q4: How long can the device operate on battery power in the field?

The instrument is equipped with a built-in 24V/7Ah DC power supply that provides up to 6 hours of continuous field operation. The device also supports direct 220V AC power input, and the battery can be recharged by switching to battery mode while connected to AC power.

Q5: What test methods are available and can the device be connected to a PC?

The pre-locator supports multiple test methods including low voltage pulse, flashover, audio, acoustic-magnetic synchronization, valley value, peak, and electromagnetic induction methods. The instrument features a communication port for local data output to a PC, enabling further analysis and report generation.

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 XHGG502A has been a great addition to our cable maintenance equipment. We use it for underground cable fault detection, and it has significantly reduced troubleshooting time. The operation is simple, the waveform analysis is clear, and the measurement results are reliable. It helps our team locate faults faster and restore power more efficiently. A very practical tool for field engineers

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.
