GE Multilin T60 Transformer Protection System

Key Benefits

• Secure High-Speed Protection: Compliant with IEEE C37.91 for various transformer applications.
• Advanced IEC 61850 Implementation: Supports Ed. 1 and Ed. 2, complete settings via SCL files, and flexible process bus support (IEC 61850-9-2LE, IEC 61869, or IEC 61850-9-2 Hardfiber), ensuring interoperability and optimizing device management with reduced ownership costs.
• Routable GOOSE (R-GOOSE): Enables wide area protection and control applications by extending GOOSE messages beyond the substation.
• Enhanced Security: Adaptive 2nd harmonic restraint algorithm and independent harmonic detection element for improved transformer energization and inrush protection.
• Advanced Connectivity: Three independent fiber or copper Ethernet ports, advanced 1 microsecond time synchronization via LAN with IEEE 1588 support.
• Sensitive Ground Fault Protection: Provides low-impedance differential protection down to 5% of winding to prevent transformer damage.
• Phasor Measurement Unit (PMU): Supports IEEE C37.118 (2014) and IEC 61850-90-5 for synchrophasor measurements.
• Advanced Cybersecurity Features: Includes "CyberSentryTM" to meet modern industry requirements.
• Application Flexibility: Offers multiple I/O options, high density I/O, programmable logic, modularity, and customization.
• Integrated Display: Large, full-color display for real-time visualization and control of protected bay, bay mimic, annunciator functionality, and graphical phasor visualization.

Applications

• Transformer asset monitoring, loss-of-life, aging factor, hottest spot analysis.
• Suitable for transformers with up to six windings in ring bus or breaker-and-a-half configurations.
• Reliable protection for three-phase transformers, autotransformers, reactors, split-phase, and phase angle regulating transformers.
• Can be used standalone or integrated into automated substation control systems.
