Description
　　1. When configuring subsystem monitoring, it can be set up in a redundant configuration with the subsystem monitoring system.
　　2. Without any subsystems, the system can independently perform comprehensive parameter monitoring for substations of all voltage levels, ranging from 10 kV to 750 kV.
　　3. Modular configuration technology;
　　4. A fully customized human-machine interface tailored to the system configuration;
　　5. The display interface size can be customized to suit different substation levels;
　　6. High-resolution, high-brightness true-color industrial-grade TFT touchscreen;
　　7. Equipped with multiple communication interfaces, including USB, Ethernet, RS232/485, and CAN.
　　8. Low-level CAN bus communication;

　　1. It can measure the voltages of two incoming feeders, busbar voltage and current, the status of input circuit breakers, busbar tie‑breaker status, ATS status, lightning protection status, and more.
　　2. Can monitor the status signals of 16 feeder circuits;
　　3. It can be connected to a three-phase energy meter to acquire busbar input power, power factor, frequency, and various electrical energy quantities.
　　4. Supports six operating modes, with automatic or manual control of ATS operation;
　　5. It features multiple protection functions, such as overload protection and ground fault protection, among others.
　　6. Built-in real-time clock with 1 ms resolution for recording event timestamps;
　　7. Interlocking switching prevents fault propagation;

　　1. Comprehensive power supply parameter management
　　2. A single module integrates functions for discrete signal detection, insulation monitoring, and current measurement.
