GE Multilin T60 Transformer Protection System
The GE Multilin T60 Transformer Protection System, also cataloged as the T60 Transformer Protection Relay, operates as a dedicated hardware component for transformer differential protection, control, and measurement within electrical substation protection networks. The relay processes CT and VT inputs, executes protection algorithms, and provides trip outputs and communication interfaces for transformer applications.
PRP, HSR, RSTP support with redundant Ethernet options
Time Synchronization
IEEE 1588 PTP, IRIG-B, SNTP
Display Interface
Integrated full color display with bay visualization functions
Industrial Control Platform Communication Characteristics
The T60 incorporates GE Multilin UR platform architecture with modular hardware expansion and configurable I/O scaling. The system supports deterministic network communication functions through IEC 61850 services, including GOOSE messaging and sampled value processing. Firmware flash compatibility within the UR hardware platform supports controlled software maintenance procedures while maintaining configured protection settings.
The relay architecture supports programmable logic, modular contact expansion, and high-density I/O configurations. Backplane bus communication velocity and hardware resource allocation are managed according to the UR platform design for protection processing and signal exchange between internal modules.
Frequently Asked Questions
Q: Does the T60 support modular CT and VT input expansion? A: Yes. The T60 hardware architecture supports modular input configurations with up to 24 CT inputs and 6 VT inputs according to the selected hardware arrangement.
Q: What communication interfaces are available for substation integration? A: The T60 supports IEC 61850 Ed. 1 and Ed. 2, GOOSE, sampled values, DNP 3.0, Modbus RTU/TCP, and IEC 60870-5-104 communication protocols.
Q: What power supply ranges are supported by the relay? A: The T60 supports high range power supplies of 110-250 V DC / 110-240 V AC and low range power supplies of 24-48 V DC.
Field Installation Guidelines
Install the T60 in a suitable protective relay panel with proper mechanical support and access for wiring inspection. CT and VT circuits should use dedicated terminal connections with correct polarity identification and separation from high-energy conductors.
Communication wiring should follow industrial shielding practices. Cable shields should be terminated according to the substation grounding design to reduce electromagnetic interference. Ethernet connections should maintain separation from power wiring and follow the selected redundancy topology requirements.
Before energization, verify auxiliary power wiring, CT shorting provisions, VT isolation points, trip output circuits, and digital input assignments. Confirm protection settings, logic configuration, and communication parameters before placing the relay into service.
