DEIF RMF-112D Frequency protection relay

The DEIF RMF-112D frequency protection relay is an advanced device produced by DEIF for generator protection. By monitoring the frequency of the generator, the relay realizes under-frequency and over-frequency protection, ensures that the generator works within the normal operating range, and prevents the failure and damage caused by abnormal frequency.

The following is a description of some features and functions of the DEIF RMF-112D frequency protection relay:

Frequency monitoring: The RMF-112D frequency protection relay monitors the frequency of the generator in real time. It ensures that the generator operates within the set normal frequency range by making precise measurements of the frequency in the grid. When a frequency anomaly is detected, the relay takes appropriate protective measures to prevent damage to the generator.

Underfrequency and overfrequency protection: The RMF-112D relay has underfrequency and overfrequency protection. When the frequency of the generator is below or above a set threshold, the relay will act quickly to cut off the power or issue an alarm to avoid the generator operating at an abnormal frequency, thereby protecting the generator from damage.

Adjustable parameters: RMF-112D frequency protection relay has the function of adjustable parameters. The user can set the threshold of underfrequency and overfrequency, as well as the operation time and mode of the relay according to the specific application requirements. This flexibility allows relays to adapt to different generator and grid conditions, providing more precise protection.

Communication and interface functions: RMF-112D frequency protection relays support 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 RMF-112D frequency protection relay has undergone rigorous quality control and environmental adaptability testing to ensure stable and reliable operation in a variety of harsh industrial environments.
