English: ABB RET670 transformer protection relay module
ABB RET670 Transformer Protection Relay Module

The RET670 module is usually installed in the relay protection device of the substation and obtains the operation data of the transformer through the current transformer (CT) and the voltage transformer (VT). A variety of protection functions are integrated inside the module, which can protect the transformer from over current, over voltage, overheating, grounding fault and other faults.

Main features and advantages
Powerful: integrates a variety of transformer protection functions, such as differential protection, overcurrent protection, overvoltage protection, gas protection, etc.
High precision: the use of high-precision measurement technology to ensure the accuracy of the protection action.
High reliability: Industrial grade design, with high reliability.
Flexible configuration: The configuration software can be flexibly set to adapt to different transformer types and operating conditions.
Rich communication functions: support a variety of communication protocols, easy to integrate with the host system.
