ABB REB670 en-US ANSI User Documentation

The ABB REB670 is a protective IED (Intelligent Electronic Device) designed for use in power systems with voltages up to 15kV. It is part of the Relion protection and control family of products offered by ABB Technology Ltd.

The REB670 provides comprehensive protection, control, measurement, and supervision for generators, transformers, motors, and transmission lines. It employs advanced signal processing and fault location techniques to minimize trip times and improve system reliability.

• Protection functions include overcurrent, earth-fault, distance, frequency, voltage, and differential protection.
• Control functions include automation and remote control capabilities.
• Measurement functions provide real-time data on voltage, current, power, energy, and harmonics.
• Supervision functions allow for monitoring and diagnosis of device performance and system status.

The REB670 operates using the IEC 61850 communication standard for efficient data exchange between devices in the power system. It can also communicate over a variety of protocols including Modbus, DNP3.0, and IEC 60870-5-101 or -104.

The device has a user-friendly HMI (Human Machine Interface) with a LCD display, pushbuttons, LEDs, and a USB port for local configuration and data transfer. It also has a built-in web server for remote access and monitoring.

The REB670 is designed with safety features such as redundant power supplies, insulation monitoring, and temperature sensors to ensure reliable operation in harsh environments. It is compliant with international standards such as IEEE C37.90 and ANSI/IEEE C37.2.

The ABB REB670 provides advanced protection and control capabilities to enhance the performance and reliability of power systems.
