RED670

The RED670 Intelligent Electronic Device (IED) is engineered for the protection, monitoring, and control of overhead lines and cables. Additionally, this IED can manage transformer feeders, generators, and transformer blocks, providing extensive functionality with configurable options and expandable hardware to meet specific requirements.

Delivered pre-configured, type-tested, and set with default parameters, the RED670 IEDs enable fast and efficient commissioning. These IEDs are equipped with complete functionality suited for single-pole breaker or multi-breaker arrangements with single or three-phase tripping. If necessary, they can be easily adapted to meet the specific requirements of your power system. The wide application flexibility makes these IEDs an excellent choice for both new and retrofit installations.

The RED670 IEDs feature phase-segregated current differential protection with excellent sensitivity for high-resistive faults and secure phase selection for up to five line terminals. Two- or three-winding power transformers can be included in the protected zone.
