Grid Solutions Multilin T60 Full-Featured, Multiple-Winding Transformer Protection 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. Protection & Control • Dual-slope, dual-breakpoint differential restraint characteristic, restrained and unrestrained differential • Transformer overexcitation overload and inhibit, thermal overload protection, 2nd Harmonic inrush and Inter-turn fault detection 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. • Five-zone backup distance protection with power swing detection and load encroachment function • Protection and control functionality in one box, reducing the number of devices • 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 • High density inputs/outputs to support the control of many switchyard assets – all from one powerful device • Integrated large, full color display, for real-time visualization and control of the protected bay Cyber Security • CyberSentry™ provides high-end cyber security aligned to industry standards and services (NERC® CIP, AAA, Radius, RBAC, Syslog) Advanced Communications • 3 independent Ethernet ports for simultaneous & dedicated network connections with IEEE 1588 support • Supports IEEE C37.111-1999/2013, IEC 60255-24 Ed 2.0 COMTRADE standard • IEC 61850-9-2LE/IEC 61869* networked or IEC61850-9-2 Hardfiber process bus support • Direct I/O for secure, high-speed exchange URs for DTT & pilot-aided schemes • 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 Monitoring & Metering • Reliable and secure protection for three-phase transformers, autotransformers, reactors, split phase and phase angle regulating transformers • P&M class synchrophasors of voltage, current, and sequence components • Stand-alone or component in automated substation control system • Advanced recording capabilities with highcapacity event recor

T60 Transformer Protection System Differential vs. Restraint Characteristic (ld vs.lr) Differential Current (Id) while exceeding the settable pickup level, an operand is asserted, which can be used to block such sensitive elements. Overexcitation Inhibit Break Point 2 Transition Region The settings for the dual-slope, dual-breakpoint characteristic provides higher flexibility for shaping up the characteristic and achieving better sensitivity and security. that may occur due to external disturbances, such as transformer inrush or near generator faults, without sacrificing speed or...

T60 Transformer Protection System For time synchronization purposes, this Process bus module can become an IEEE 1588 slave clock (61850-9-3 profile) or a 1588 Grand Master clock which removes the need of external time sources connected to the process bus network. Customers who may not be using GE MU devices, could use MU from other vendors. Interoperability with MU from other vendors is expected when they comply to the mentioned standards. IEC 61850-9-2 HardFiber Process Bus The IEC 61850 Process Bus module is designed to interface with the Multilin HardFiber System, allowing bi-directional...

T60 Transformer Protection System Monitoring and Metering The T60 includes high accuracy metering and recording for all AC signals. Voltage, current , and power metering are built into the relay as a standard feature. Current and voltage parameters are available as total RMS magnitude, and as fundamental frequency magnitude and angle. For power quality applcations, harmonic measurements (up to the 25th) for voltage and current are available. T60 can monitor, calculate and log hottestspot temperature, aging factor and loss-of-life data over a long period. This data, combined with economic...
