ALSTOM PIB310 Transformer Differential Protection Relay

Advanced Grid Protection Systems

Main Features and Benefits

The ALSTOM PIB310 delivers precision transformer protection through its advanced differential algorithms and multi-criteria restraint characteristics. Engineered for critical power infrastructure, this relay provides comprehensive protection for transformers ranging from distribution units to large power transformers. Its adaptive harmonic blocking system prevents false tripping during transformer energization while maintaining sensitivity for genuine internal faults.

Key operational advantages include:

• Advanced restraint characteristics: Multi-slope percentage differential protection with adaptive bias settings
• Inrush detection: Advanced 2nd harmonic blocking with adjustable thresholds for reliable operation
• Comprehensive monitoring: Real-time thermal modeling with overload prediction and tap changer supervision

The PIB310 features dual-redundant processing architecture for fail-safe operation in critical applications. Its large graphical LCD provides clear visualization of transformer parameters and protection status, while front-accessible USB ports enable convenient configuration without cabinet access. Compliant with IEC 61850 standards, this relay seamlessly integrates into modern substation automation systems with GOOSE messaging for high-speed protection coordination.
