What Is The Watchdog On The Low Voltage Column Circuit Breaker?

Lv Pole Mounted Circuit Breakers with watchdog means that the circuit breaker has intelligent controller function, and the watchdog function is:

1. Automatically cut off single-phase grounding fault in the user area (with watchdog function)
When a single-phase grounding fault occurs in the user branch line, the circuit breaker automatically opens; the responsible user is out of power while the adjacent users are not out of power.

2. Automatically isolate the phase-to-phase short circuit fault in the user area (with watchdog function)
When a phase-to-phase short circuit fault occurs in the user branch line, the circuit breaker immediately opens and locks after the substation circuit breaker or recloser protection trips. After the substation recloses, the other users on the feeder quickly resume power supply.

3. Quickly locate the fault point (with watchdog function)
The user branch line fault causes the circuit breaker protection to operate. After the responsible user is out of power, the user can actively report the power outage. The power company can quickly locate the fault point and quickly dispatch personnel to the site for investigation. Or after the optional communication module, the circuit breaker can automatically report the fault information and line status information through the information channel (wireless or wired).
