ABB RET670

The ABB RET670 module is a high-performance transformer protection relay from ABB and belongs to the RELION family of products. It is mainly used in the power system to protect the transformer, to prevent overcurrent, overvoltage, grounding fault and other abnormal conditions, to ensure the safe and stable operation of the transformer.

Product name and model
Product name: transformer protection relay

Model: RET670
The RET670 module is usually installed in the relay protection device of the substation, and can monitor the operation status of the transformer in real time by measuring the current, voltage and other parameters in the transformer. Once a fault is detected, the module quickly sends a signal that triggers the corresponding protective action, thereby protecting the transformer from damage.

Product parameters and specifications
The specific parameters of the RET670 module may vary according to different configurations and application scenarios. The following lists some common parameters:

Rated voltage: refers to the maximum system voltage that the module can withstand.
Rated current: refers to the maximum current that the module can measure.
Input signal: Measure voltage, current, temperature and other signals.
Output signal: control relay, alarm signal, etc.
Protection function: over current protection, over voltage protection, ground fault protection, differential protection, etc.
Communication interface: Supports a variety of communication protocols, such as IEC 61850.
