XHGG555 Vehicle mounted cable diagnosis and fault location system

General features

Topology
Highly integrated and highly automated digital software cable fault location system, with the option to integrate variable frequency resonance, oscillation wave (partial discharge) and ultra-low frequency (dielectric loss) functions

Modularity
All test units are designed to be relatively independent and modular, and functional modules can be added or removed at will; if a single function fails, it will not affect the use of other functions.

Control
Most operating modes and system functions are achieved through a control unit, and each unit module can also be operated individually.

Graphical User Interface: Graphical interface, more intuitive and easy to operate.

Operation: Turn and click a single knob (jog dial) on the control unit.

System: Windows

Date management: General database

Data Synchronization: Universal Serial Bus

Control unit

System unit composition

1. Use DC or high-voltage pulse to make the cable fault point flash over and discharge

2. Use the traveling wave reflection principle to make a rough measurement of all types of cable main insulation faults

3. Use the acoustic and magnetic synchronization method to make a precise measurement of all types of cable main insulation faults

4. Use the electromagnetic induction principle to accurately find the unknown cable path and depth

5. Use the bridge method to make a rough measurement of all outer sheath faults and the main insulation (especially water ingress faults)

6. Use the step voltage method and clamp current method to accurately locate the outer sheath fault

7. Use the constant power principle to reduce the resistance of the ultra-high resistance fault

8. Use the encoding method + phase method to identify multiple cables

9. Use the remote control method to confirm the final puncture of the cable (finally, personal safety is absolutely guaranteed)

10. Use ultra-low frequency (0.1Hz) to perform insulation withstand voltage test and dielectric loss test on the cable

11. Use Ohm's law to measure the quality of the cable in a coil

12. Necessary tools and equipment on the cable detection test site (megohmmeter, measuring instrument, electrician tools)
