Main Features
Feeder Protection
The REF615 provides comprehensive protection for medium-voltage feeders. Typical functions include:
- Phase overcurrent protection
- Earth-fault protection
- Directional overcurrent/earth-fault functions
- Thermal overload protection
- Breaker-failure protection
- Automatic reclosing
- Over/undervoltage functions
- Frequency-related protection
These functions allow the relay to detect feeder faults and initiate circuit-breaker operation to isolate the affected section.
Integrated Feeder Control
The relay combines protection, measurement, control and supervision in a single IED. It can monitor breaker status and provide local or remote circuit-breaker control, reducing the requirement for separate protection and control equipment.

IEC 61850 Substation Communication
REF615 is designed for modern digital-substation architectures. Depending on the configuration, it can communicate using IEC 61850, including high-speed GOOSE messaging for interlocking and protection-related signals.
Other supported protocols can include Modbus RTU/TCP, DNP3 and IEC 60870-5-103/104.
Measurement and Monitoring
The relay provides electrical measurements such as:
- Phase currents
- Residual/earth-fault current
- Voltages
- Active and reactive power
- Power factor
- Energy
- Frequency
These measurements can be used locally or transmitted to SCADA and substation automation systems.
Disturbance and Event Recording
The REF615 platform provides event and disturbance recording functions that are useful for fault analysis, commissioning and preventive maintenance.
Recorded information can help engineers determine the sequence of events preceding a feeder trip and verify protection performance.
Application Fields
Medium-Voltage Distribution
The primary application is MV feeder protection in utility distribution substations. The relay can protect outgoing feeders and coordinate with upstream/downstream protection devices.
Industrial Power Distribution
The REF615 is suitable for industrial switchgear supplying motors, transformers, process equipment and auxiliary systems.
Power Plants
It can be used to protect auxiliary and distribution feeders within power-generation facilities.
Oil & Gas and Petrochemical
The relay can protect critical distribution feeders supplying pumps, compressors, motors and other plant loads while providing communication with the facility’s electrical SCADA system.
Renewable Energy
REF615-based feeder protection can be incorporated into collection and distribution networks associated with renewable-energy facilities.
Engineering and Integration
ABB REF615 relays can be configured and engineered using ABB PCM600. The relay’s programmable logic capabilities allow engineers to implement customized interlocking, breaker-control and automation sequences.
A typical application architecture is:
CT/VT → REF615 → Circuit Breaker → Substation Control/SCADA
For digital-substation installations:
REF615 ↔ IEC 61850 Station Bus ↔ SCADA / Station Controller
