The MultilinTM T60 transformer protection system is a comprehensive three-phase transformer relay designed to protect medium and large power transformers. The T60 provides automatic or user-definable magnitude reference winding selections for CT ratio matching, and performs automatic phase shift compensation for all types of transformer winding connections. The T60 algorithm allows the user to enable removal of the zero-sequence current even for delta connected transformer windings, accommodating transformers with a variety of grounding configurations.
Key Benefits
• Secure, high-speed protection for transformers, compliant with IEEE C37.91 for maximum asset life
• Improved security for transformer energization and inrush provided through an adaptive 2nd
harmonic restraint algorithm
• Sensitive ground fault protection provides low-impedence differential protection down to 5% of the
winding to limit transformer damage
• Integrated transformer thermal monitoring for asset management and maintenance optimization
• Embedded Synchrophasor measurement capabilities (per IEEE C37.118), eliminating the need for
dedicated PMUs and support for synchrophasor multi-cast (per IEC 61850-90-5) reducing bandwidth
and communications infrastructure costs
• 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.
• Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and
comprehensive process bus support (IEC 61850-9-2LE or IEC 61869* or IEC 61850-9-2 Hardfiber) ensures
interoperability, device managing optimization and reduced cost of ownership
• Routable GOOSE (R-GOOSE) enables customer to send GOOSE messages beyond the substation, which
enables WAPC and more cost effective communication architectures for wide area applications
• Increased network availability via failover time reduced to zero through IEC 62439-3 “PRP” support
• Supports IEEE C37.111-1999/2013, IEC 60255-24 Ed 2.0 COMTRADE standard
Applications
• Transformer asset monitoring using hottest spot, loss-of-life and aging factor• 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
