Product Features

Three remote functions : telemetry (including DC), remote signaling, remote control;
Protection functions : three-phase three-section overcurrent protection function, zero sequence protection function, reclosing and blocking reclosing functions;

Intelligent distributed logic function : realizing the on-site clearing of faults, automatic isolation of faults, automatic transfer of power supply, automatic recovery of power supply in non-faulty sections; logical manual, automatic reset, etc.
Remote / local operation : The remote / local closing and closing operations are mutually blocked, and the control exit is controlled by the soft and hard pressure plates.
Power supply function : dual power supply switching, when AC power failure, automatic seamless switching to backup power supply, and at the same time, automatic management (battery activation, alarm, protection) function of backup power;
Communication function : multiple network ports and serial ports, supporting multiple communication protocols; wireless communication: wireless communication through touch notebook;
Wireless communication : can communicate wirelessly by touching the notebook;
Status indication : there are obvious local status indication signals such as operation, communication, and line failure;
Data processing function : Arbitrary configuration and combination of data sent from the master station; distribution transformer load rate, three-phase imbalance, telemetry over-limit, extreme value, qualified rate statistics, etc .;

Fault detection : realizing the on-site clearing of faults, automatic isolation of faults, automatic transfer of power supply, automatic recovery of power supply in non-faulty sections; logical manual, automatic reset and other functions;
