Secondary equipment constitutes the monitoring, control, and protection system in power systems. It is responsible for real-time monitoring, precision control, and safety protection of primary equipment's operational status, and both are indispensable to each other.
Electrical secondary equipment does not directly participate in electrical energy transmission, but its core value lies in achieving precise regulation and control of primary equipment through automation and intelligent technologies.
Typical equipment includes:
● Relay Protection Devices: Analyze fault signals in real time and trigger protection actions within milliseconds
● Measuring Instruments & Monitoring Systems: Dynamically collect voltage and current data to support intelligent decision-making
● Automation Control Systems: Enable remote operation and fault self-healing to improve operational efficiency
● Communication & Data Processing Units: Ensure efficient information flow and support digital management
