Product Description
Cable Fault Tester | TDR Cable Fault Pre-Locator | XHGG501B
Product Description

The cable fault tester is a special instrument for measuring and analyzing the fault status and fault distance of power cables. It adopts modern electronic technology to realize signal filtering, acquisition, data processing, graphic display and graphic analysis, and completes cable speed measurement, cable length test, cable fault distance test and resistance test.

This cable fault tester is suitable for low-resistance, short-circuit, open-circuit and disconnection faults of power cables, coaxial cables, street light cables, buried wires, etc. of various materials with different cross-sections and different media, as well as high leakage resistance and flashover high resistance faults. The technical parameters meet the standard requirements of DL/T 849.1 (General Technical Conditions for Special Tester for Power Equipment Part 1: Cable Fault Flash Tester) and JJF1042 (Calibration Specification for Cable Fault Tester).

Applications & Target Audience: Engineered for shipyard and marine engineering electrical teams, hospital and medical campus facility management units, defense installation maintenance teams, and oil and gas field electrical maintenance departments that pre-locate low-resistance, open-circuit, disconnection, high-resistance leakage and flashover faults in power cables up to 32km.
Product Features
  • Industrial-grade 5.7-inch dual-color screen with clear waveform and menu display;
  • Single-chip centralized control, push-button operation, strong anti-interference ability;
  • Functions such as distance measurement, speed measurement and resistance measurement;
  • The micro-printer is integrated with the host, which can print test waveforms and test reports at any time;
  • Fully automatic continuous sampling, waveform capture is timely and accurate;
  • With low-voltage pulse sampling method and flashover sampling method;
  • Built-in large-capacity battery pack, easy to use;
  • Adopt protective case, not lower than IP54.

The XHGG502 tester works flawlessly for indoor building wiring jobs. It quickly located hidden cable faults inside Warsaw’s Złota 44 high-rise. Compact, precise amid tangled inter-floor wires and saves us tons of repair time.

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.
