ABB Relion Feeder Protection Architecture

REF601 integrates protection, monitoring, and control functions in a single relay. Its configured protection functions are intended for overhead line and cable feeder applications in solidly earthed, resistance-earthed, and isolated networks.

The relay provides serial communication through Modbus RTU and IEC-103. These interfaces support connection to supervisory or substation control systems where the corresponding communication configuration is implemented.

The unit uses the same configuration software platform as other ABB Relion protection and control products. Application-specific parameters can therefore be configured within the intended feeder protection application.

Frequently Asked Questions

Q: What communication protocols are supported by the REF601?

A: The supplied data specifies Modbus RTU and IEC-103 serial communication.

Q: What feeder types can the REF601 protect?

A: The supplied data specifies overhead lines and cable feeders in solidly earthed, resistance-earthed, and isolated networks.

Q: What is the continuous contact carry capability?

A: The specified continuous contact carry value is 8 A.

Field Installation Guidelines

Install the REF601 according to the applicable ABB installation documentation and the switchgear manufacturer's wiring requirements. Verify the relay supply voltage and polarity before energization.

Keep protection, communication, and power wiring separated where required by the switchgear design. Route communication conductors away from high-current or high-noise conductors when practical.

Terminate cable shields according to the site's protection and EMC grounding scheme. Verify that protective earth and signal reference connections comply with the installation design before commissioning.

Before placing the feeder into service, verify the configured protection parameters against the feeder design, confirm communication settings for Modbus RTU or IEC-103, and perform functional checks of the connected protection and control circuits.
