Transformer protection REG670 1MRK502019-BZH Feeder protection device
The REG 670 is designed for the protection, control and monitoring of generators and generators and can be used in power plants of all sizes. The device has a comprehensive function library that can meet the requirements of most generator applications. A large number of analog input channels and comprehensive function library make the device integrate multiple functions in one. In a typical application, two devices can perform all functions and provide a high degree of redundancy. The REG 670 can also protect shunt reactors.
The protection function library includes differential protection for generators, auxiliary transformers and generators. The stator grounding protection includes 95% stator grounding protection based on fundamental wave and 100% stator grounding protection with three harmonic braking characteristics. Among them, 100% protection uses voltage differential method, which has high sensitivity and high safety. In addition, the device is also equipped with out-of-step protection, loss of magnetic protection, rotor grounding protection, negative sequence current protection and so on.
The generator differential protection in the REG 670 is suitable for applications where the DC time constant is large and the trip time is short.
The protection function can be used for a variety of occasions, so a single device can have multiple protected objects. The main protection of a generator can also protect its auxiliary power transformer. In this way, the cost is greatly reduced.
REG 670 implements the monitoring function, and the data during operation can be displayed on the man-machine interface.
The flexibility of the application makes the REG 670 an excellent choice for both new and old stations. The serial data communication uses optical fiber connection to ensure that the device is protected from electromagnetic interference.
