【英文介绍】
RED670 is a line differential protection device, which is part of the Relion family of products designed to meet the high requirements of power system protection.
Key features and functions of the RED670 include:
Suitable for power systems of all voltage levels, it can be used to protect, control and monitor overhead lines and cables, including heavy duty lines and multi-terminal lines.
Support single-phase, two-phase and three-phase tripping mode, and provide phase differential protection, with excellent sensitivity and phase selection function.
It can be adapted to different network structures, including impedance grounded or directly grounded systems, and can also be used to protect a variety of networks, including series compensation systems.
With backup distance protection function, when the communication channel is interrupted, it can be used as a selective backup protection.
Equipped with current protection function, can effectively detect the fault current in the line, but also has voltage protection function, can monitor the voltage change on the line.
In addition, RED670 is not only a protection device, but also an intelligent electronic device that integrates control and monitoring. It can monitor the power system, including secondary system monitoring
and frequency protection functions.
RED670 also has a service port for monitoring and adjusting software variables, supports RED670 communication, and provides configuration, calibration, troubleshooting, and alarm/shutdown monitoring.
Overall, the RED670 is a powerful and stable protection device that can be used to improve the reliability of power systems and provide integrated protection, control and monitoring solutions.
