MVAX31S1DC0754A | Distance Protection Relay

ALSTOM Network Protection Relay MVAX31S1DC0754A

Main Features and Advantages

Advanced Distance Protection: The ALSTOM MVAX31S1DC0754A delivers precise impedance-based protection with configurable quadrilateral and mho characteristics. Its adaptive zone reach logic automatically adjusts protection boundaries based on network conditions, preventing unnecessary tripping during transient events like power swings.

Synchronized Phasor Measurement: With integrated PMU functionality, this relay provides real-time synchrophasor data (IEEE C37.118 compliant) for system-wide visibility. This enables superior fault location accuracy (±1% of line length) and supports wide-area protection schemes.

Power System Intelligence: Beyond primary protection, the MVAX31S1DC0754A offers comprehensive monitoring capabilities including power quality analysis, sequence-of-events recording, and energy metering. The 64 COMTRADE format fault records facilitate rapid post-event analysis.

Cybersecurity and Reliability: Designed for critical infrastructure protection, this relay features secure protocols with authentication and encryption support. The rugged design withstands severe EMI conditions per IEEE 1613 standards and operates reliably across industrial temperature ranges.

Application Areas

Essential for transmission line protection in utility substations, industrial power networks, and renewable generation facilities. Particularly effective for EHV applications (up to 500kV), long transmission corridors, series-compensated lines, and interconnected systems requiring high-speed selective tripping.
