GE Multilin T60 Transformer Protection System

$1.00

The T60 is designed for various power applications, including autotransformers, generator step-up transformers, split-phase, angle regulating transformers and reactors. It uses multiple current and voltage inputs to provide primary protection and backup protection of transformers, including differential, ground differential, five distance zones, phase, neutral, and ground overcurrent, under and overvoltage, under and overfrequency, over-fluxing, and breaker failure.

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 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 a superior adaptive 2nd harmonic restraint algorithm
  • 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 (2011) and IEC 61850-90-5 support
  • CyberSentry™ provides high-end cyber security aligned to industry standards and services (NERC CIP, AAA, Radius, RBAC, Syslog)
  • Reduced relay-to-relay wiring and associated installation costs through high-speed inter-relay communications
  • 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

UR Switch Module:

In addition to providing high-speed connectivity directly to your Universal Relay, the UR Switch Module provides an additional 4 fiber Ethernet ports, for connection to other relays in the system as well as upstream connectivity. It also provides 2 RJ45 copper Ethernet ports which can be used to connect local devices such as PCs, meters, or virtually anything else in the system.

The UR Switch Module provides a simple way to add fully-managed Ethernet networking to your relays and devices without the need for additional hardware or a dedicated communications cabinet and includes all of the management and features that come with all MultiLink managed switches which can be easily integrated into a network that has other Ethernet switches.

When used in a ring topology with other UR Switch Modules or MultiLink Switches, the UR Switch Module can be configured to use MultiLink’s Smart RSTP feature to provide industry-leading network recovery for ring topologies, at a speed of less than 5ms per switch.

Interoperability with Embedded IEC 61850

Use the T60 with integrated IEC 61850 to lower costs associated with generator protection, control and automation. GE’s leadership in IEC 61850 comes from thousands of installed devices and follows on years of development experience with UCA 2.0.  The T60’s IEC 61850 Process Bus module is designed to interface with the Multilin HardFiber System, allowing bi-directional IEC 61850 fiber optic communications. The HardFiber System is designed to integrate seamlessly with existing Universal Relay applications, including protection functions, FlexLogic, metering and communications.
