ABB 1MRK002814-AB

2. Function Features

• Protection Functions: It comes with a variety of protection functions including differential protection, over – current protection, over – voltage protection, etc. There is also an automatic reclosing function. This ensures stable operation of power systems.
• Control and Monitoring: It can be used for the control, protection, and monitoring of different types of bays in power networks. It has the ability to handle multi – breaker/multi – bay control in a single device. It also integrates voltage control function and offers pre – configured fault recording solutions. Additionally, it supports optional single – phase or three – phase tripping and reclosing, as well as horizontal communication of digital and analog data between devices.

3. Application Scenarios

• Power Systems: It is widely used in power systems, especially beneficial for power systems with series compensation or HVDC. It can protect and control key equipment and components in power systems, enhancing system stability and reliability.
• Substation Automation: Specifically applied in substation automation systems to monitor and control intervals between various electrical devices such as circuit breakers and disconnectors. It also finds use in power transmission line monitoring and management, as well as distribution network automation control.

4. Supported Industrial Protocols

• It supports multiple communication protocols like Modbus and IEC 61850. These protocols enable seamless connection with various power equipment and efficient data transfer. The IEC 61850 – 8 – 1 Ed 1 or Ed 2 station bus function can be fully utilized, especially in control system applications.

5. Expandability

• Given its support for standard communication protocols like Modbus and IEC 61850, it can easily interface with other devices in the power system ecosystem. Its modular design, which allows for single – device handling of multi – breaker/multi – bay control and integration of functions, also indicates good expandability. As the power system grows or new components are added, the REC670 can be integrated into the new setup, either by connecting with new devices through the supported protocols or by incorporating additional functions based on its modular design.
