ABB RET670 - Transmission Transformer Prrotection

RET670 IEDs provide customized or pre-configured protection solutions for any type of transformer and shunt reactor application. The customized RET670 gives you the freedom to select functionality entirely according to your needs. The pre-configured RET670 variants simplify handling since the basic functionality is included and pre-configured. If needed, you can add optional functions to increase the functionality of the pre-configured RET670 IEDs to meet the specific requirements of your transformer or shunt reactor.

The extremely fast differential protection function with automatic CT ratio matching and vector group compensation, makes RET670 the ideal solution for the most demanding applications. Furthermore, one RET670 IED can be extended to contain two differential protection functions to protect the most advanced system configurations. This transformer protection IED is designed to operate correctly over a wide frequency range in order to accommodate power system frequency variations during disturbances and generator start-up and shut-down. It has very low requirements on the main CTs, and no interposing CTs are required.

RET670 features also several functions for local and remote apparatus control on all sides of the transformer. Secure bay and station wide interlocking allows you to avoid dangerous or damaging switchgear operations and to ensure personnel safety.
