GE VERNOVA | TRANSFORMER PROTECTION SYSTEM | MULTILIN T35
The T35 is designed to provide basic transformer protection functions for variety of transformer applications. It uses multiple current inputs to provide primary protection and backup protection of transformers, including differential, phase and ground overcurrent. The relay can be configured to accept up to 6 sets of current inputs to provide proper differential restraint for applications with three-winding transformers with windings configured in dual-breaker arrangements.
Applications
- Combined protection for transformer and small bus zone, including breaker-and-a-half and ring bus diameters
- Stand-alone or component in automated substation control system
- Applicable for transformers with windings in a ring bus or breaker-and-a-half configuration
Key Benefits
- Secure high-speed transformer differential protection in a cost-effective package
- Improved security for transformer energization and inrush
- Application flexibility for transformers with up to 6 sets of CTs
- Robust network security enabling Critical Infrastructure Protection
- 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
- 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
Key Features
Complete IEC 61850 Process Bus solution providing resource optimization and minimizing total P & C life cycle costs.- Three independent 100Mbps Ethernet ports enable purpose specific LAN support that eliminates latency effect of heavy traffic protocols on mission critical communication services
- Embedded IEEE 1588 time-synch protocol support eliminates dedicated IRIG-B wiring requirements for IEDs
- Direct I/O secures high-speed exchange of binary data between URs
- Increase network availability by reducing failover time to zero through IEC62439-3 PRP, HSR or dual HSR support
Advanced Communications
The T35 provides advanced communications technologies for remote data and engineering access, making it easy and flexible to use and integrate into new and existing infrastructures. Direct support for fiber optic Ethernet provides high-bandwidth communications allowing for low-latency controls and high-speed file transfers of relay fault and event record information. The available three independent and redundant Ethernet options provide the means to create fault tolerant communication architectures in an easy, cost-effective manner.The T35 supports the most popular industry standard protocols enabling easy, direct integration into DCS and SCADA systems.
