1) Electrical parameter acquisition: Real-time collection of electrical parameters such as voltage, current, zero-sequence voltage, zero-sequence current, power, power factor, and frequency.

2) Switch status monitoring: Monitor the open and closed states of circuit breakers, load switches, isolating switches, and other equipment.

3) Short-circuit fault detection: Detect short-circuit and ground faults in the line, automatically or manually isolate the faulty section, and reduce the scope of power outages.

4) Remote opening and closing: Control the opening and closing operations of circuit breakers or load switches via remote commands.

5) Self-Diagnosis and Maintenance: Automatically detect the equipment status, promptly identify faults, and support remote upgrades and maintenance.

6) Sequence of Events (SOE) recording: Record the precise time sequence of events such as switch position changes and protective actions.

7) Communication Function: Exchange data with the main station or other terminals, and support multiple communication protocols such as IEC60870-5-101/104, DNP3, etc.

8) Alarm function: Trigger local and remote alarms when abnormalities are detected (such as overcurrent, overvoltage, communication interruption,etc.).

9) Intelligent load management: Optimize load distribution based on load demand and price signals.
