Product Overview

The Woodward LR20025 (MFR13) serves as a critical safeguarding component for wind turbines, distributed power generation, and complex grid interconnection points. This high-performance protection relay monitors electrical parameters with surgical precision to prevent equipment damage during abnormal grid conditions. Engineered as the primary technological successor to the legacy MFR300, the LR20025 optimizes system uptime by integrating advanced fault detection algorithms into a compact, vibration-resistant chassis.

Technical Specifications

The following table outlines the core engineering parameters for the LR20025:

Engineering Advantages

• Direct Legacy Migration: The LR20025 specifically replaces the MFR300 series. Engineers can upgrade existing turbine infrastructures without extensive rewiring or cabinet modifications, significantly reducing labor costs during retrofitting.

• Harsh Environment Durability: Woodward builds this relay to withstand the high-vibration profiles and thermal fluctuations inherent in wind turbine nacelles. The ruggedized housing ensures long-term signal integrity where standard relays fail.

• Precision Grid Synchronization: The device provides high-speed processing of grid synchronization data. It prevents hazardous "out-of-phase" connections, protecting both the generator and the local utility infrastructure.

• Space-Efficient Geometry: The compact 96mm width allows for high-density installation in crowded control cabinets, a vital feature for distributed energy containers where space is at a premium.

FAQs

Q: Can the LR20025 directly replace the older Woodward MFR300 series?

A: Yes. Woodward designed the LR20025 (MFR13) as a modern replacement for the MFR300. It offers enhanced fault detection capabilities while maintaining compatibility with typical wind turbine infrastructure requirements.

Q: What specific protections does the MFR13 logic provide?

A: The relay monitors and protects against over/under voltage, over/under frequency, phase displacement, and rate of change of frequency (ROCOF). This comprehensive suite ensures the turbine disconnects safely during grid instability.

Q: Does this product come with a warranty and origin documentation?

A: We provide this unit as 100% Brand New and original Woodward hardware. It includes a standard 12-month warranty and we can provide the Certificate of Origin (COO) to verify its manufacture in the USA.

Q: How does the unit handle vibration in wind turbine applications?

A: The LR20025 features a ruggedized internal architecture designed to withstand the continuous mechanical stress and harmonic vibrations found in wind power environments, ensuring reliable switching and monitoring over its entire service life.
