In modern power systems, the reliability and intelligence level of feeder protection directly affect the safe and stable operation of the power grid. ABB's latest REF65 relay, with its breakthrough design and powerful functions, is redefining the standards of feeder protection, providing more efficient and accurate protection for the operation of the power grid.

Compared with traditional protection devices, the REF615 relay breaks through the limitations of single protection functions, achieving multifunctional integration, and can meet the needs of overcurrent protection, grounding protection, fault location, and remote monitoring simultaneously, greatly improving the reliability and flexibility of the system.

Support for multiple communication protocols such as IEC 6180, Modbus, and DNP3, achieving seamless integration with SCADA systems, and providing real-time data transmission and remote operation capabilities for the power system.
