The
REF615E-E is an enhanced medium-voltage (MV) feeder protection relay, part of ABB’s industry-leading Relion® 615 Series. Engineered to address the evolving needs of smart grids and industrial power systems, this relay combines robust protection capabilities with advanced digital features—delivering precise fault detection, seamless connectivity, and proactive system monitoring.
Ideal for MV feeders in utility networks, industrial plants, and commercial infrastructure, the REF615E-E ensures fast fault isolation, minimizes downtime, and supports integration with modern digital substation architectures. Its rugged design and flexible configuration make it suitable for both new installations and retrofits, aligning with global standards for power system safety and efficiency.
Equipped with advanced protection algorithms—including adaptive overcurrent settings and directional earth fault detection—to pinpoint faults accurately, avoiding unnecessary feeder tripping and improving grid stability.
Gigabit Ethernet ports and support for IEC 61850 Ed. 2 (including Sampled Values) enable integration with digital substations and smart grid platforms, facilitating real-time data exchange and remote control.
±0.1% accuracy for current and voltage measurements ensures reliable data for load monitoring, energy management, and grid optimization—eliminating the need for separate metering devices.
A 3.5-inch color LCD display with touch-sensitive navigation simplifies on-site configuration, while a web-based HMI allows remote access via any browser—reducing setup time and maintenance visits.
Withstands wide temperature ranges (-40°C to +70°C), vibration, and electrical interference, making it suitable for harsh environments like outdoor substations, industrial plants, and remote renewable energy sites.
Built-in condition monitoring (e.g., power supply health, relay self-tests) and event logging (up to 2000 fault records) provide early warnings of potential issues, extending equipment lifespan and reducing unplanned downtime.
Customizable logic blocks and support for add-on functions (e.g., synchrocheck, load shedding) allow tailoring to specific network needs, while compatibility with ABB’s Relion® ecosystem enables easy expansion.
