REF615E
The ABB REF615E excels in real – world electrical environments, thanks to its comprehensive and advanced protection features. The distance protection function accurately locates faults along transmission lines by measuring impedance, enabling targeted isolation of faulty sections and reducing the impact on the power grid. The auto – reclosing feature automatically attempts to restore power after a fault clearance, enhancing the reliability of the power supply. The power swing detection function is crucial in preventing unnecessary tripping during power swings, maintaining the stability of the grid. With its ultra – fast tripping times, the REF615E can swiftly clear faults, protecting valuable electrical equipment and avoiding cascading failures.
REF615E
In terms of communication, the ABB REF615E offers versatile connectivity options. The support for IEC 61850 via Ethernet enables seamless integration into modern substation automation systems, facilitating interoperability with other compliant devices and enabling efficient data exchange, remote monitoring, and control. PROFIBUS DP and Modbus TCP provide compatibility with a wide range of existing industrial and power system devices.
