The REG670 is an intelligent electronic device (IED) designed to protect and monitor generators, prime movers and boost transformers in a variety of power stations. Manufactured by Hitachi Energy (formerly ABB), the device has a variety of protection functions, including overcurrent, overload, short circuit, ground failure, etc., to ensure the safe operation of power equipment and systems. At the same time, the REG670 can achieve differential protection of generators, transformers and other equipment to ensure the current balance within the equipment.
The REG670 supports long-distance communication, and can communicate with remote monitoring system and SCADA system through the communication interface to achieve remote monitoring and control. In addition, the REG670 can record event and fault information to help operation and maintenance personnel analyze system operation and the cause of failure.
The REG670 is suitable for power system protection and control, and is often used in substations, power plants and other power facilities. The specific installation requirements, debugging methods, maintenance, etc., should follow the product instructions.
Overall, the REG670 is a comprehensive, high-performance digital protective relay that can quickly and accurately detect faults in the power system and take appropriate measures to protect the safe operation of power equipment.
The protection function of REG670 is very comprehensive and specific, mainly including the following aspects:
Comprehensive protection features: The REG670 provides a variety of protection features, including over current, over load, short circuit, ground failure, etc., to ensure the safe operation of power equipment and systems.
Differential protection: The REG670 can be used to achieve differential protection of generators, transformers and other equipment to ensure the current balance within the equipment.
Overcurrent and undervoltage/overvoltage protection: This protection function can monitor changes in electrical parameters such as current and voltage, and issue protective actions in time according to preset thresholds to prevent equipment from being damaged due to excessive current or abnormal voltage.
