The main application scenario of feeder protection measurement and control devices is feeder protection in power systems. In the power system, the feeder is the intermediate link between the power source and the load. If the feeder fails, it will affect the normal operation of other links in the power grid. Therefore, feeder protection and measurement devices must be installed in the power system to quickly remove faults and ensure the stable operation of the power grid. It should be noted that when installing feeder protection and measurement devices, different types of feeder protection and measurement devices should be selected based on specific application scenarios and system requirements, and standardized operation and maintenance should be carried out to ensure the stable and safe operation of the power system. The feeder protection measurement and control device is an important component of the protection equipment in the power system, which is widely used. Its function is to quickly remove faults in the event of feeder faults, ensuring the stable operation of the power grid.
