DEIF MDR-2 Multi-differential relay

The DEIF MDR-2 multi-differential relay is an advanced protection device for internal short-circuit protection of generators and other critical electrical equipment. The relay combines differential protection and short circuit protection to respond quickly in the event of failure and protect equipment from damage.

The following is a description of some features and functions of DEIF MDR-2 multi-differential relays:

Differential protection: The MDR-2 relay has differential protection to detect internal short-circuit faults in generators or other electrical equipment. By comparing the currents on both sides of the device, MDR-2 can quickly identify unbalanced currents and cut off power in the event of a failure, thereby preventing damage to the device.

Short circuit protection: In addition to differential protection, the MDR-2 also has short circuit protection. When the short-circuit current in the circuit is detected to exceed the set value, the relay will quickly cut off the power supply to limit the damage of the short-circuit current to the equipment and system.

Adjustable trip characteristics: The trip characteristics of the MDR-2 relay can be adjusted, and the user can set the trip current value according to the specific application requirements. This allows relays to adapt to different equipment and system requirements, providing more precise protection.

Integrated LCD display: The MDR-2 relay is equipped with an integrated LCD display that displays all measured and calculated values. This enables users to intuitively understand the operating status and fault information of the device, facilitating troubleshooting and maintenance.

Communication and interface functions: MDR-2 relays support a variety of communication interfaces, such as Ethernet, Modbus, etc., for data exchange and communication with other control devices and monitoring systems. This enables users to implement remote monitoring, data acquisition and control functions.

Programmable and configurable: MDR-2 relays support programming and configuration functions, and users can set relay parameters and functions according to specific needs. This allows the relay to adapt to different industrial environments and control requirements.
