RET670 RET670 digital protection relay

The RET670 digital protection relay offers customized or pre-configured protection solutions for any type of transformer and shunt reactor application. It provides fast and selective protection, monitoring and control functions for a wide range of power equipment, such as transformers, autotransformers, generators, phase-shifting transformers, special railway transformers and shunt reactors.

Main feature
Multifunctional protection: The RET670 offers a variety of protection functions, including overcurrent protection, undervoltage protection, overvoltage protection, ground fault protection, etc., which can be configured and customized according to the needs of different electrical equipment and motors.
High-precision measurement: Using advanced digital signal processing technology, it can measure electrical parameters such as current and voltage with high precision.
Fast response: with a fast response speed, it can quickly cut off the fault circuit when the fault occurs, and prevent the expansion of the fault and equipment damage.
Flexible configuration: Support flexible configuration and programming, function Settings and parameters can be adjusted through software.
Remote monitoring and control: Support for remote monitoring and control functions, allowing operators to remotely monitor the status of the power system and perform necessary operations.
Differential protection function: Includes differential protection to detect current differences in the system in order to identify and isolate faults in a timely manner.
Event recording and alarm: With event recording function, it is used to record the events and faults that occur in the system for subsequent analysis and troubleshooting.
