【英文介紹】

The RET670 is a digital protective relay that is mainly used to protect various devices in power systems, such as transformers, cables, generators, etc., from damage.

The RET670 relay has a variety of functions and features to meet the protection needs of different electrical equipment and motors.

The RET670 uses advanced digital signal processing technology to measure electrical parameters such as current and voltage with high precision. By monitoring and analyzing the changes 

of these parameters in real time, the relay can accurately judge the operating state of the electrical equipment and the motor, and issue protective actions in time. This high precision measurement 

enables the RET670 to provide more reliable and effective protection.

The RET670 has a fast response speed. When a fault occurs, it can quickly cut off the fault circuit to prevent the expansion of the fault and equipment damage. This rapid response capability helps 

reduce outage times and the risk of equipment damage, improving the stability and reliability of the power system.

The RET670 also supports flexible configuration and programming. According to the actual needs and the characteristics of the power system, users can customize the protection scheme through

 the software to set the functions and adjust the parameters. This flexibility allows the RET670 to adapt to different application scenarios and protection needs.

The RET670 also features remote monitoring and control. Operators can remotely monitor the status of the power system and perform necessary operations. This remote monitoring and control 

function enables RET670 to be easily integrated into the automation system to achieve automatic control of the power system and improve the efficiency and reliability of the system.

In the field of application, RET670 is mainly used to protect various types of transformers and reactors. It has low requirements for the main current transformer and does not require an intermediate 

current transformer, making the installation and use easier. In addition, the RET670 provides selective and rapid protection, monitoring and control of two - and three-reel transformers, autotransformers, 

phase-shift transformers, transformer banks, special railway supply transformers and shunt reactors.

Overall, ABB's RET670 digital protective relay is a powerful, stable and easy to integrate protection device. It provides reliable protection and control for the power system, ensuring the safe operation of 

electrical equipment and motors. Whether in terms of measurement accuracy, response speed, configuration flexibility, or remote monitoring capabilities, the RET670 shows its excellent performance and 

a wide range of applications.
