The XHHG502 ARC cable fault locator is suitable for measuring the low resistance, short circuit, open circuit and disconnection faults of various materials of different cross-sections and different media, high-frequency coaxial cables, local telephone cables, street light cables, and buried wires. Prevent leakage and high-resistance flashover faults. Super powerful cable management system, automatic report generation.
1. It can detect the high and low resistance faults of all cables of 35KV and below, and it has a wide range of applications.
2. The instrument adopts the latest technology of embedded industrial computer and the most advanced "eight pulse method" in the world.
It got impact high-pressure flashover method and low-pressure pulse method.
3. Any high-impedance fault presents the simplest waveform characteristics similar to a low-voltage pulse short-circuit fault, which is very easy to interpret.
4. With user-friendly software, full English menu and screen touch button operation. The button definition is simple and clear. The measurement method is simple and fast.
5. The success rate of failure detection, test accuracy and test convenience are better than any domestic testing equipment.
6. Ultra-high brightness, large LCD screen as the display terminal, can be clearly observed in the environment of direct sunlight
Screen waveform. The instrument has powerful data processing capabilities and a friendly display interface.
7. With the function of handwriting board, when the waveform is stored, the personnel, locations and fault characteristics of the field test can be stored.
Information such as the test process is directly handwritten into the saved document.
8. With extremely safe high-voltage protection measures. The flash tester will not crash or be damaged in an impact high-pressure environment.
9. Has a standard printer USB interface.
10. Simple operation and high reliability. Has a very high cost performance.
11. No test blind zone.
12. Built-in polymer lithium battery power supply, can test cable open circuit and low resistance short circuit fault in no power environment.
