ABB REC670 1MRK004814-AC

Function Features

• Powerful Protection Functions2: It has a variety of protection functions, including high – set instantaneous phase and ground over – current, directional or non – directional delayed phase and ground over – current, thermal overload, and under – and over – voltage functions. It can also realize synchronism control, interlock breaker closing, and has auto – reclose functionality and breaker failure protection, which can effectively ensure the safe operation of the power system.
• Accurate Fault Detection and Location2: With disturbance recording and fault locator features, it can conduct independent post – fault analysis, help identify primary disturbances and single failures within the protection system, and provide detailed fault reports and diagnostics, which is convenient for quick corrective actions and preventive maintenance.
• Flexible Control Modes2: Control can be executed remotely via SCADA/station or locally through HMI. Various control configurations are available, allowing either one control IED per bay or shared usage across multiple bays. Interlocking modules are suitable for common switchgear arrangements, ensuring secure operations through the select – before – execute principle.
• User – friendly Configuration: It is equipped with user – friendly software, and the configuration process can be simplified through a graphical tool, reducing the setup time and effort. The intuitive interface also enables operators to easily access device status, alarm, and trip information.
• High – level Cyber Security: It has features such as secure communication channels, password protection, and configurable access rights, which can effectively ensure the security of the power system and prevent unauthorized access.

Application Scenarios

• Distribution Networks: It can be used in distribution networks to protect and control distribution transformers, feeders, etc., and ensure the stable operation of the distribution network.
• Industrial Systems8: Applied in industrial power systems, it can protect and monitor important equipment such as generators, transformers, and cables in factories, and improve the reliability of industrial production.
• Renewable Energy Plants: Suitable for solar, wind, hydro – power and other renewable energy systems, it can monitor and protect the power generation equipment in the system, and ensure the stable power generation and grid – connection of renewable energy.
• Substations: Play an important role in substations, be responsible for the protection and control of various bay equipment, and can work with other intelligent electronic devices to realize the automation of substations.
