DEIF MTR-3F-215 Generator Protection Relay​

Description

Product Overview: DEIF MTR-3F-215 Generator Protection Relay​​

The DEIF MTR-3F-215 is a advanced, compact, and fully programmable generator protection relay designed for marine and offshore applications. As a critical component in a vessel’s power management system (PMS), its primary function is to continuously monitor a 3-phase generator set and protect it from a wide range of electrical faults and abnormal operating conditions. By ensuring the generator operates within safe parameters, it prevents damage to the generator itself and maintains the stability and availability of the entire shipboard electrical network.

Part of DEIF’s renowned MTR-3 series, the 215 model is engineered for reliability and ease of integration, embodying DEIF’s commitment to quality and safety in the maritime industry.

​​Key Features & Benefits​​

​​Comprehensive Protection Suite:​​

• Offers a complete set of protection functions in a single unit, including:
  • ​​Overcurrent & Short Circuit:​​ (50/51, 50I) Protection against phase and neutral faults.
  • ​​Earth Fault Protection:​​ (51N/67N) For both measured and isolated systems.
  • ​​Under/Over Voltage:​​ (27/59) Monitors generator terminal voltage.
  • ​​Under/Over Frequency:​​ (81O/U) Protects against speed governor failures.
  • ​​Reverse Power:​​ (32) Essential for protecting prime movers (e.g., diesel engines) when parallel-running generators.
  • ​​Differential Protection (Optional):​​ High-impedance differential protection for maximum generator safety.

​​Advanced Measurement & Monitoring:​​

• Provides highly accurate, real-time measurement of all essential electrical parameters: V, I, Hz, kW, kVAR, kVA, kWh, PF, and more.
• This data is crucial for both the relay’s internal logic and for external systems to make informed load-sharing and power management decisions.

​​Versatile Programmable Logic (PLC):​​

• Features a built-in Programmable Logic Controller (PLC) functionality. This allows for extensive customization of control sequences, interlocking, and automation tasks (e.g., auto-start/stop of gensets, breaker control) without the need for external hardware.

​​Clear Human-Machine Interface (HMI):​​

• Equipped with a high-resolution graphical display that provides clear visualization of measurements, status, and single-line diagrams.
• Intuitive navigation buttons and a rotary knob simplify on-site configuration, commissioning, and troubleshooting.

​​Robust Marine Design & Certifications:​​

• Designed and tested to withstand the harsh marine environment, including resistance to vibration, shock, humidity, and wide temperature fluctuations.
• ​​Certified by all major classification societies​​ (e.g., DNV GL, ABS, Lloyd’s, BV, etc.), making it approved for use on virtually any commercial vessel worldwide.

​​Communication Capabilities:​​

• Supports multiple industry-standard communication protocols such as ​​Modbus RTU​​ (RS485) and ​​CANopen​​, enabling seamless integration into a vessel’s integrated automation system (IAS) or power management system (PMS).
