Overview
The RED670 IEDs are delivered pre-configured, type tested and set with default parameters for fast and efficient commissioning. These IEDs are equipped with complete functionality adapted for single pole breaker or multi-breaker arrangement with single or three phase tripping. If needed, they can also 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.
It provides an extensive functionality with configuration opportunities and expandable hardware to meet your specific requirements.
For maximum reliability of your power system
Line differential protection RED670 IED belong to the Relion protection and control product family. The Relion product family offers the widest range of products for the protection, control, measurement and supervision of power systems. To ensure interoperable and future-proof solutions, Relion products have been designed to implement the core values of the IEC 61850 standard. With Hitachi Energy’s leading-edge technology, global application knowledge and experienced support network, you can be completely confident that your system performs reliably – in any situation.
The customized REC670 gives you the freedom to select the functionality entirely according to your needs. The pre-configured REC670 variants simplify handling since the basic functionality is included and pre-configured. If needed, you can add optional functions to easily increase the functionality of the REC670 IEDs to meet the specific requirements of your switchyard.
REC670 integrates advanced voltage control for transformers in a substation in a single IED. The IEDs feature a large HMI for local control and instant access to important data, such as settings, events and disturbance information.
The outstanding I/O capability in REC670 enables control of several bays with complete measurement with only one IED. For instance, one REC670 IED is capable of handling control of all apparatuses in one entire diameter in 1 ½ breaker arrangement including breaker failure protection for all breakers.
