MULTILIN T60

Key Benefits

• Secure high-speed protection for transformers, compliant with IEEE C37.91
• Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and flexible process bus support (IEC 61850-9-2LE, IEC 61869 or IEC 61850-9-2 Hardfiber) ensures interoperability, device managing optimization and reduced cost of ownership
• Routable GOOSE (R-GOOSE) enables GOOSE messages going beyond the substation, which enables wide area protection and control applications
• Improved security for transformer energization and inrush provided through an adaptive 2nd harmonic restraint algorithm and an independent harmonic detection element
• Three independent fiber or copper Ethernet ports for simultaneous/dedicated network connections with advanced 1 microsecond time synchronization via LAN with IEEE 1588 support
• Sensitive ground fault protection provides low- impedance differential protection down to 5% of the winding to limit transformer damage
• Phasor Measurement Unit (synchrophasor) according to IEEE C37.118 (2014) and IEC 61850-90-5 support
• Advance Cyber security features “CyberSentryTM” that helps meet modern industry requirements
• Application flexibility with multiple I/O options including high density I/O, programmable logic, modularity, and specific customization
• An integrated large, full color display, provides real-time visualization and control of the protected bay, via a bay mimic as well as annunciator functionality and graphical visualization of phasors

Applications

• Transformer asset monitoring using loss-of-life, aging factor, hottest spot
• Applicable for transformers with up to six windings in a ring bus or breaker-and-a-half configuration
• Reliable and secure protection for three-phase transformers, autotransformers, reactors, split-phase and phase angle regulating transformers
• Stand-alone or component in automated substation control system
