DC System Ground Fault Locating and Alarm System

 

Features


1. Cortex-M3 STM32 Master chip, high integration anti-interference abilit, low power dissipation
2. Menu operation with humanization design
3. Parameters set via menu, alarms all through sound and light output or relative dry contact output
4. Accurate measure identify bus and branch grounding, detect grounding fault in two or more branches.
5. Test and monitor all branches grounding
6. Make circle test of all the branches, or select one branch to test
7. Store and display the latest 5 times bus insulation warning records
8. Test two sections bus ripple voltage and ripple coefficient
9. No consistence request or direction request to CT polarity
10. RS485 interface technology for signal sampling, effective transmission distance reaches 1000 meters
11. With RS232, RS485 communication interface for connecting with external equipment
12. With 100M Ethernet interface
13. Fast branch testing
14. Can set AC sneaking in alarm threshold ( AC RMS)
15. Real-time track info zero processing technology for AC signal channeling into DC fault test and alarm
16. Color screen with LCD self-protection function
17. With simple multi-machine connection function for complicated multilevel DC system
18. Real time measure power ripple, voltage, ripple coefficient in all ranges.

      It also can effectively record the AC content in DC power source.
