The ABB REG670 is a digital protective relay commonly used for the protection, control and monitoring of power systems. Here are some of its main features and functions:

• Comprehensive protection function: provides over current, over load, short circuit, ground fault and other protection to ensure the safe operation of power equipment and systems. For example, in the event of an overcurrent fault, it can quickly cut off the faulty circuit and protect the equipment from overload damage.

• Differential protection: It can be used to achieve differential protection of generators, transformers and other equipment to ensure the current balance inside the equipment. For example, in the operation of the transformer, it can effectively detect the fault situation of the internal winding.

• Long-distance communication: With a communication interface, it can communicate with remote monitoring system, SCADA system, etc., to achieve remote monitoring and control. It is convenient for the staff to understand and control the operating status of the equipment remotely.

• Event record: Records events and faults for O&M personnel to analyze system running status and fault causes. This helps locate and resolve problems quickly, improving system reliability and maintenance efficiency.

• User-friendly graphical interface: An intuitive graphical user interface makes operation and monitoring easier. Operators can more intuitively view equipment status and parameters, reducing the difficulty of operation and the possibility of misoperation.

• Adaptive parameter setting: With adaptive parameter setting function, intelligent adjustment can be made according to the system running status and changes. It can better adapt to different working scenarios and operating conditions, improve the accuracy and reliability of protection.

ABB REG670 has a wide range of applications:

• Power plant protection: used to protect generators, transformers and related equipment in power plants to ensure the safe and stable operation of power plants.

• Network protection: Applied to the protection of lines and equipment in the power grid, to ensure the stability and security of the power grid, and to prevent failures from causing a large area of impact on the power grid.

• Industrial power systems: In industrial power systems, plant equipment, motors and power distribution systems can be protected from industrial production interruptions and equipment damage due to power failures.

• Ac and DC systems: Suitable for AC and DC power systems, providing comprehensive protection functions for different types of power systems.

• Renewable energy: in wind and solar power generation systems, used to protect inverters and equipment connected to the power network, promoting the efficient use of renewable energy and stable access to the grid.

• Railway electrification system: used in the railway electrification system to ensure the safe and reliable operation of the electrification system and ensure the normal transport order of the railway.
