RED670 – Transmission Line Differential Protection | Maximum Reliability for Power Systems

The RED670 IED (Intelligent Electronic Device) from ABB is designed for the protection, monitoring, and control of overhead lines, cables, transformer feeders, and generator blocks. This versatile IED offers a wide range of functions and is highly configurable to meet specific power system requirements, making it a reliable solution for both new installations and retrofits.

Pre-configured, type-tested, and set with default parameters, the RED670 IED ensures quick and efficient commissioning. It provides comprehensive protection features, adaptable to single pole breakers or multi-breaker arrangements, and can handle single-phase or three-phase tripping.

The RED670 IED offers phase-segregated current differential protection with excellent sensitivity to high resistive faults. Its secure phase selection supports up to five line terminals, and two- or three-winding power transformers can be integrated into the protected zone. With its robust application flexibility, this IED is ideal for modern and retrofit power systems.

The RED670 IED is part of the Relion protection and control family, which is renowned for offering the widest range of protection, control, measurement, and supervision products. These IEDs are built to comply with the IEC 61850 standard, ensuring interoperability and future-proofing. With Hitachi Energy’s cutting-edge technology and global application expertise, you can rely on RED670 IEDs to deliver optimal performance and ensure the reliability of your system under any condition.
