RET670 - Optimized transmission applications

The RET670 ied offers customized or pre-configured protection solutions for any type of transformer and shunt reactor application. The customized RET670 gives you the freedom to choose features entirely according to your needs. The preconfigured RET670 variant simplifies processing because the basic features are included and preconfigured. If desired, you can add optional features to increase the functionality of the pre-configured RET670 ied to meet the specific requirements of your transformer or shunt reactor.

Extremely fast differential protection, automatic CT ratio matching and vector group compensation make the RET670 the ideal solution for the most demanding applications. In addition, a RET670 IED can be extended to include two differential protection features to protect the most advanced system configurations. The transformer protection IED is designed to operate correctly over a wide frequency range to accommodate frequency changes in the power system during interference and generator start-up and shutdown. It has very low requirements for primary ct and does not require ct insertion.

The RET670 also has a variety of features for local and remote device control on all sides of the transformer. Secure bay and station wide interlocks allow you to avoid dangerous or destructive switchgear operations and ensure personnel safety.

The RET670/RET650 ied is part of the Relion Protection and control product family. The Relion product family offers the broadest range of products for the protection, control, measurement and supervision of power systems. To ensure interoperable and future-proof solutions, Relion products are designed to implement the core values of the IEC 61850 standard. With Hitachi Energy's leading technology, global application knowledge and experienced support network, you can be completely confident that your system will operate reliably under any circumstances.
