ABB REG670
Main Features and Advantages
Precise Protection
The REG670 uses advanced digital signal processing techniques. This allows for extremely accurate measurement of electrical parameters such as current and voltage. By constantly monitoring these values in real – time, it can precisely determine the operating state of electrical equipment. For instance, it can detect even the slightest deviation from normal parameters, which enables it to quickly identify potential faults. When a fault is detected, its fast response mechanism ensures that the faulty circuit is cut off promptly. This not only protects the equipment from further damage but also helps prevent the spread of faults within the power system, thus reducing the risk of large – scale outages.
Customizable Protection
One of the key strengths of the REG670 is its flexibility in protection configuration. Users can tailor the protection functions according to the specific needs of their electrical equipment. For different types of motors, transformers, or other electrical devices, the overcurrent, undervoltage, and other protection settings can be adjusted. This customization ensures that the relay provides the most appropriate protection, maximizing the lifespan and reliability of the protected equipment.
Easy Integration
The REG670 supports multiple communication protocols, making it highly compatible with various other devices and systems in a power network. It can seamlessly integrate with control systems, data acquisition units, and other intelligent devices. This enables data sharing and exchange, allowing for better monitoring and management of the overall power system. For example, it can send real – time status information to a central control room, facilitating remote monitoring and troubleshooting.

Application Field
The ABB REG670 finds extensive applications across various industries. In industrial settings, it is used to protect large – scale manufacturing equipment. For example, in a steel mill, it safeguards high – power motors and electrical transformers. These motors are crucial for the operation of heavy machinery like rolling mills. The REG670 ensures that any electrical faults, such as overcurrent caused by sudden mechanical jams, are quickly detected and rectified, preventing costly equipment breakdowns and production stoppages.
In power generation plants, whether they are thermal, hydro, or wind – powered, the REG670 plays a vital role. It protects generators from abnormal electrical conditions. For instance, during sudden load changes in a wind power plant, the REG670 can detect overvoltage or undervoltage situations and take appropriate actions to safeguard the generator. This helps in maintaining stable power generation and grid connectivity.
Even in commercial buildings, the REG670 is used to protect the electrical distribution system. It ensures that the lighting, heating, and cooling systems, as well as other electrical appliances, are protected from electrical faults. This provides a reliable power supply to tenants, enhancing the overall functionality and comfort of the building.
