RED670 - Differential protection for transmission lines for maximum power system reliability.The RED670 IED (Intelligent Electronic Device) is designed for
the protection, monitoring and control of overhead lines and cables. In addition, this IED is capable of handling transformer feeders, generators and
transformer banks. It offers a wide range of functions, configuration opportunities and scalable hardware to meet your specific requirements.
The ABB RED670 is a protection relay from ABB designed for the protection of power equipment in high voltage power systems.The RED670 is typically
used in substations and power transmission and distribution systems, where its main function is to monitor the status of the power system, protect and
control abnormalities in order to ensure reliable operation of the system.
Below are some of the common features and functions of the RED670 protective relay:
Differential protection: The RED670 supports differential protection, which is used to detect differences in current at different locations to identify internal
faults in electrical equipment such as transformers.
Overcurrent protection: Used to monitor if the current exceeds a set threshold to prevent damage to equipment due to current overload.
Overvoltage and Undervoltage Protection: Monitors whether the voltage exceeds or falls below a set threshold to protect equipment from voltage anomalies.
Frequency Protection: Used to monitor the frequency of the power system to prevent problems caused by frequency deviations from the normal range.
Synchronisation Detection: The RED670 can be used to detect synchronisation conditions in a power system to ensure that equipment in the system is
operating in a synchronised state.
Communication Interface: Supports communication with other devices and monitoring systems to monitor and control the power system in real time.
Event Logging and Reporting: The RED670 is able to log events that occur in the power system and generate reports in order to analyse the performance
of the system and the cause of the event.
