Core Functions of the ABB REF615R Numerical Relay

The ABB REF615R Protection Relay executes several critical functions that safeguard electrical distribution systems:

• Overcurrent Protection (ANSI 50/51): This fundamental protection function detects excessive current conditions that could indicate short circuits or overload situations. The relay offers both instantaneous and time-delayed overcurrent protection with highly accurate trip characteristics. That can be customized to coordinate with upstream and downstream protective devices.
• Earth Fault Protection (ANSI 50N/51N): Specialized earth fault protection algorithms detect ground faults with exceptional sensitivity. Even in high-impedance grounded systems. This function is particularly valuable in preventing equipment damage and personnel safety hazards associated with ground faults.
• Directional Protection (ANSI 67/67N): For applications involving parallel feeders or interconnected networks, directional protection ensures. That only the relay closest to the fault operates, maintaining service to unaffected portions of the system. The ABB Numerical Relay calculates fault direction with high accuracy using advanced algorithms.
• Voltage Protection (ANSI 27/59): The relay continuously monitors system voltage levels and initiates protective actions when undervoltage or overvoltage conditions are detected. This protection is essential for safeguarding voltage-sensitive equipment and maintaining power quality.
• Frequency Protection (ANSI 81O/81U): Frequency variations can indicate serious system disturbances or generator instability. The ABB REF615R Feeder Protection relay monitors frequency deviations and executes load shedding or other protective schemes when thresholds are exceeded.
• Breaker Failure Protection (ANSI 50BF): If a circuit breaker fails to interrupt fault current as commanded, the breaker failure function initiates backup tripping to isolate the faulted section through adjacent breakers, preventing cascading failures.
• Thermal Overload Protection (ANSI 49): By modeling the thermal characteristics of protected equipment, this function prevents damage from prolonged overload conditions that might not trigger instantaneous overcurrent protection.

Applications of the ABB REF615R Protection Relay

The versatility of the ABB REF615R Numerical Relay makes it suitable for numerous applications across various industries:
