ABB RET670 1MRK002816-AB Transmission transformer

DESCRIPTION

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.
