GE Multilin UR Platform Generator Protection Architecture

The G60 operates on the GE Universal Relay modular hardware structure with configurable rack slots for processor, CT/VT acquisition, digital input/output, power supply, and communication modules. The relay processes generator electrical quantities through dedicated current and voltage measurement channels and executes protection logic through the embedded CPU and DSP resources.

The UR platform supports deterministic Profinet / EtherNet-IP style industrial network concepts through dedicated communication modules where configured, while the G60 implementation uses GE-specific Ethernet and serial communication interfaces for protection data exchange, configuration access, and monitoring functions.

The modular architecture allows I/O density scaling through selectable expansion modules, enabling additional contact inputs, trip outputs, transducer interfaces, and auxiliary control circuits without changing the primary relay enclosure.

Frequently Asked Questions

Q: What CT and VT signal ranges are supported by the G60 relay?
A: The relay accepts configurable CT secondary inputs of 1 A or 5 A and VT inputs from 50 V to 240 V phase-to-neutral nominal values according to the selected hardware configuration.

Q: Does the G60 support modular I/O expansion?
A: Yes. The UR hardware structure provides multiple module slots for digital input, relay output, and auxiliary interface expansion.

Q: What power supply range is available for this model configuration?
A: The specified power supply module supports 88-300 VDC or 88-264 VAC at 50/60 Hz.

Field Installation Guidelines

Install the relay in the specified horizontal rack mounting position with appropriate mechanical support for the 19 inch enclosure format. Maintain separation between CT/VT wiring, digital signal wiring, and communication cables to reduce electromagnetic coupling.

Terminate protective earth connections according to the installation grounding scheme. Use shielded communication cables where required, with cable shields connected according to site grounding practice. Verify CT polarity, VT phase sequence, and terminal assignments before energizing measurement circuits.

Confirm the selected power supply input range before connection. During commissioning, verify module seating, backplane connections, communication addressing, and protection element configuration through the relay configuration software.
