GE Multilin Feeder Protection and IEC 61850 Communication Features

The F650BFBF1G0HICE integrates feeder protection logic, bay control functions, and communication processing within the GE Multilin 650 platform. The relay supports deterministic protection processing for ANSI functions including 50/51 phase overcurrent, 50N/51N ground overcurrent, 67/67N directional overcurrent, 27/59 voltage protection, 81 frequency protection, 50BF breaker failure, and 79 autoreclose control.

The integrated logic engine supports IEC 61131-3 programmable control functions for interlocking, transfer schemes, load shedding, and breaker control sequences. Communication functions include IEC 61850 Edition 2, Modbus RTU/TCP, DNP3, and IEC 60870-5-104 protocol operation through the configured communication interfaces.

Frequently Asked Questions (FAQ)

Q: Does the F650BFBF1G0HICE support hot-swap replacement during energized operation?
A: The available documentation does not specify hot-swap capability. Replacement should follow standard protection relay isolation procedures with auxiliary supply and field wiring disconnected before removal.

Q: What is the digital input and output hardware capacity of this configuration?
A: The configuration includes 16 configurable digital inputs and 8 programmable relay outputs. Input filtering and output assignment are configured through the relay settings.

Q: Which communication interfaces are supported by this model configuration?
A: This model supports IEC 61850 Edition 2, Modbus RTU/TCP, DNP3, and IEC 60870-5-104 communication protocols through its configured Ethernet and serial interfaces.

Field Installation Guidelines

Install the relay in a suitable protection panel enclosure with controlled grounding, ventilation, and access clearance according to the installation requirements of the GE Multilin 650 series.

Terminate CT and VT wiring using dedicated protection terminal blocks. Maintain separation between low-level communication wiring and high-energy current or voltage circuits to reduce electromagnetic interference.

Connect the protective earth terminal using an appropriate grounding conductor. Apply shield grounding practices for communication cables according to the selected protocol installation standard.

Verify auxiliary supply polarity and voltage range before energization. The HI power supply option accepts 110-250 V DC and 120-230 V AC input ranges within the specified operating limits.

Perform secondary injection testing after installation to verify protection elements, trip outputs, breaker control logic, and communication data exchange.
