Product Features

Three remote functions: telemetry, remote signaling, and remote control;

Protection functions: three-phase three-section overcurrent protection function, zero sequence protection function, reclosing and blocking reclosing function;

Intelligent distributed logic function: achieving local fault clearing, automatic fault isolation, automatic transfer of power supply, and automatic restoration of power supply in non faulty sections; Logic manual, automatic reset and other functions;

Remote/local operation: The remote/local closing and opening operations are mutually locked, and the control outlet is controlled by the soft and hard pressing plates for on/off;

Power function: Dual power switching, automatic seamless switching to backup power supply in case of AC power loss, and automatic management (battery activation, alarm, protection) function for backup power supply;

Communication function: multiple network and serial ports, supporting multiple communication protocols;

Status indication: There are obvious local status indication signals for operation, communication, line faults, etc;

Data processing function: arbitrary configuration and combination of data sent by the main station; Distribution transformer load rate, three-phase imbalance, remote sensing exceeding limit, extreme value, qualification rate statistics, etc;

Fault monitoring: receiving and forwarding fault indicator signals; Coordinate with variable load cabinet to determine single-phase grounding fault
