2、 Main functions:

1. Protection function: Automatically identify fault currents, achieve instantaneous current quick break, * current quick break, timed overcurrent, directional overcurrent, overvoltage, undervoltage, single-phase grounding protection for low current grounding systems, as well as cold load start suppression and disconnection functions.

2. Measurement function: measure three-phase current, three-phase voltage, active power, reactive power, active power, reactive power, peak/valley power, power factor, and frequency.

3. Control function: It can achieve on-site operation and remote control, and can also operate according to pre-set plans; It can automatically locate faults, isolate faults, and quickly restore power supply to non faulty lines according to requirements, and achieve control functions such as automatic switching of backup power supply.

4. Communication function: It can report faults, operation and operation information to personnel in a timely manner through wireless public or private communication networks, supporting multiple communication methods and protocols; By holding a PDA, it is possible to modify the fixed value parameters under the pole. The controller performs self inspection after receiving instructions from the PDA and feeds back the self inspection information to the PDA terminal.

5. Data recording function: Automatically record and store information on operation, handling, and faults.

6. Synchronous opening and closing function: Based on load characteristics, it automatically searches for zero crossing points, adapts to the discreteness of switch parameters and the influence of environmental factors, achieves synchronous opening and closing, effectively suppresses operating overvoltage and closing inrush current, and is particularly suitable for switching capacitors and transformers.

7. Intelligent function: It can perform online comprehensive analysis of power grid parameters, monitor the performance parameters of circuit breakers online, program online, and cooperate with the main station of the distribution network automation system to achieve remote control and management of switchgear, and realize the functions of local, remote, or hierarchical control distribution network automation system.
