One Tap — Full Test Report. After locating a fault, tap the touch screen once. The XHGG502 generates a complete test report: waveform screenshot, cable type, detection method, test parameters, calculated fault distance, operator name, test location, and field notes. Print, export to USB, or archive for compliance — no separate PC, no manual transcription.
The XHGG502 ARC Cable Fault Pre-Locator integrates automated report generation directly into the test workflow. After waveform acquisition and fault distance analysis, the operator fills in a few fields on screen — test location, operator name, cable identification, remarks — and the instrument produces a fully formatted report with embedded waveform screenshots and all test parameters. Reports can be printed directly via USB-connected printer or exported to a USB flash drive for archiving, email distribution, or integration into project acceptance documentation. This capability transforms the XHGG502 from a standalone test instrument into a complete field documentation system, eliminating the common gap between field testing and office reporting. GB/T 18268.1, DL/T 849.1-2019, and JJF1042-2020 compliant.

In most cable fault investigation workflows, the most time-consuming step is not the test itself — it is the documentation. A field crew locates a fault in 30 minutes, then the senior engineer spends 3 hours back in the office: transcribing handwritten notes, exporting waveform files from a proprietary format, manually entering test parameters into a report template, and cross-referencing photos taken on a separate camera.
The XHGG502 collapses this to seconds. During the test session, the operator enters the relevant metadata — test location, operator, cable ID, environmental conditions, test notes — using the on-screen keyboard and stylus. These annotations are stored with the waveform file. When the test is complete, one tap generates the report. By the time the crew returns to the office, the report is on a USB drive, ready for attachment to a work order close-out or a client deliverable.
What Is in the Report| Section | Content |
|---|---|
| Test Information | Date/time, cable type (XLPE/PVC/rubber/oil-paper), detection method (LV pulse/HV flashover/multi-pulse), test length range |
| Test Results | Fault distance (meters), propagation velocity used, waveform screenshot with cursor positions, calculated error margin |
| Field Metadata | Operator name, test location, cable identification, environmental conditions, remarks |
| Instrument Data | Model XHGG502, sampling frequency 400MHz, firmware version, calibration status |
Perhaps the most underutilized capability of a report-generating test instrument is trend analysis. The XHGG502 stores all test waveforms in a searchable filing system — organized by cable name, feeder, or project. When testing the same cable on a subsequent maintenance visit, the operator opens the previous waveform file and overlays the current trace. A cable that returned a clean waveform at 5000m last year but shows a 20% reduction in propagation velocity and an emerging reflection at 3200m this year is degrading — and you know exactly where before the fault occurs.
This transforms the XHGG502 from a fault-finding tool into a predictive maintenance instrument. For utilities with regulatory inspection cycles, the report history provides auditable evidence that each cable segment has been tested on schedule, with documented results showing either a pass or a degradation trend requiring scheduled replacement.

Q: How does the built-in report generator work?
The XHGG502 captures waveform screenshots, test parameters (range, velocity, pulse width), and distance measurement results, then compiles them into a formatted digital report with a single tap. This is especially valuable for testing service providers who need to deliver formal documentation to utility clients, and for project acceptance testing where certified test records are required.
Q: What is the difference between XHGG502 and XHGG501A2?
Both feature 12.1-inch displays with 400MHz sampling and 68km range, but the XHGG502 adds the report generator and advanced waveform management functions. The XHGG502 is positioned for organizations with formal documentation requirements, while the XHGG501A2 offers the same core testing capability at a more accessible price point for users who don't need integrated report generation.
Q: What test methods are supported and how do I choose?
Low-voltage pulse method for open/short/low-resistance faults, cable length measurement, and wave velocity calibration. High-voltage flashover method (with external HV generator) for leakage high-resistance faults. ARC multi-pulse for flashover high-resistance faults. Start with LV pulse for initial diagnosis, then select the appropriate HV method based on insulation resistance test results.
Q: What accessories are needed for a complete testing workflow?
For LV pulse testing, only the XHGG502 main unit and test leads are required. For HV flashover and ARC multi-pulse testing, you need an external high-voltage pulse generator (e.g., XHHV535 series) and a pulse coupler rated for the test voltage. For precise excavation point marking after pre-location, an acoustic-magnetic pinpointer (e.g., 503D) is recommended. All XZH TEST components integrate seamlessly.
Q: Can I set up customized velocity profiles for my cable inventory?
Yes. The XHGG502 supports both preset velocity values for common insulation types (XLPE ~172m/μs, oil-impregnated ~160m/μs) and fully customizable velocity settings. For organizations managing multiple cable types, we recommend calibrating velocity on a known-length healthy phase of each cable type in your inventory and saving these profiles for faster field setup on future tests.
Q: What standards does the XHGG502 comply with?
The XHGG502 is CE and ISO certified, and complies with GB/T 18268.1 (EMC requirements for electrical test equipment), DL/T 849.1-2019 (general specifications for cable fault testers), and JJF1042-2020 (calibration specification for cable fault locators). 12-month warranty with lifetime technical support is standard.
