6. Selection Recommendations

• System Voltage & Current: Verify compatibility with your MV system’s voltage (100V–690V AC) and current (1A/5A rated) to ensure proper fault detection.
• Communication Needs: Prioritize this relay if your substation requires IEC 61850 or IEEE 1588 v2 for smart grid integration; basic applications may opt for Modbus-only models.
• Environmental Conditions: Choose the REF615E-E for outdoor/harsh environments; indoor setups with controlled climates may consider compact variants.
• Redundancy Requirements: Deploy in HSR/PRP configurations for critical feeders to eliminate single points of failure.

7. Installation & Maintenance Tips

• ESD Protection: Use anti-static wrist straps during handling to safeguard internal electronics.
• Wiring Practices: Separate control cables from high-voltage conductors to minimize EMI; follow ABB’s guidelines for shielded cable termination.
• Firmware Updates: Regularly update firmware via ABB’s Relion® Configurator to access the latest protection algorithms and security patches.
• Periodic Testing: Conduct annual functional tests using a relay test set to validate protection thresholds and communication integrity.
• Safety Protocol: Power down the system and isolate all voltage/current sources before installing or servicing the relay to prevent electric shock.
