DEIF RMC-131D Current relay

The DEIF RMC-131D current relay is a high performance protection device produced by DEIF Company, which is mainly used for the current protection of generators. The relay has differential protection to detect short circuits and winding leakage currents inside the generator and quickly cut off power in case of failure to protect the generator from damage.

The following is a description of some features and functions of the DEIF RMC-131D current relay:

Differential protection function: The RMC-131D current relay uses the differential protection principle to compare the differential current in the three phases of the generator. By measuring and calculating the current of each phase accurately, it can accurately detect the short circuit and winding leakage current inside the starting motor. Once an abnormal current is detected, the relay will act quickly to cut off the power to the faulty part, thus limiting the damage to the generator.

Multi-function and adjustable parameters: The RMC-131D is a multi-function device with many adjustable parameters that the user can configure according to the specific application needs. By adjusting the parameters of the relay, different protection functions can be realized, such as overcurrent protection, ground protection and so on. In addition, the relay also provides a wealth of measurement functions, such as RMS measurement, peak measurement, etc., to meet the user's accurate requirements for current parameters.

Fast response: In order to achieve a short response time under fault conditions, the RMC-131D current relay uses peak-based measurement. This measurement method can quickly detect the abnormal current when the fault occurs, and cut off the power in a very short time, thus minimizing the damage of the fault to the generator.

Communication and interface functions: RMC-131D current relay supports a variety of communication interfaces and protocols, such as Ethernet, Modbus, etc., to facilitate data exchange and communication with other control devices and monitoring systems. This allows users to achieve remote monitoring, data acquisition and control functions, improve the reliability and flexibility of the system.

High safety and reliability: DEIF is known for the safety and reliability of its products. The RMC-131D current relay has undergone rigorous quality control and environmental adaptability testing to ensure stable and reliable operation in a variety of harsh industrial environments. In addition, the relays are equipped with error condition indicators and LED signs for easy troubleshooting and maintenance.
