Product Dimensions：

Product Description (Detailed Explanation)

The REF615 is characterized by its compact, plug-in design, which facilitates easy installation and rapid maintenance. The “E-G” configuration typically denotes a specific functional package tailored for feeder protection with advanced earth-fault protection and additional control capabilities.

• Standardized Communication: Fully supports the IEC 61850 standard for communication and interoperability in substations, including horizontal GOOSE messaging.

• Protection Core: It provides comprehensive protection for incoming and outgoing feeders in distribution networks, including overcurrent, earth-fault, and voltage-based protection functions.

• Human-Machine Interface (HMI): Features a large graphical display that shows customized single-line diagrams (SLD), status information, and measurements.

Product Parameters (Technical Specifications)

Product Advantages (Key Benefits)

• Enhanced Safety: Includes integrated arc-flash protection (optional) to minimize damage and improve personnel safety during electrical faults.

• Plug-in Design: The removable plug-in unit allows for quick replacement or testing without disconnecting the secondary wiring, significantly reducing downtime.

• Precision Measurement: High-accuracy measurement of current, voltage, power, and energy, reducing the need for separate metering devices.

• Flexibility: Easily adaptable to different substation requirements through programmable logic and configurable function blocks.

• Reliability: Extensively tested to withstand harsh electromagnetic environments and extreme temperature variations.

Precautions (Important Notes)

• Secondary CT Circuit: Never open-circuit the secondary side of a Current Transformer (CT) while the primary is energized. This can generate lethal voltages. Always use the relay’s short-circuiting contacts during maintenance.

• Configuration Backup: Before performing firmware updates or hardware replacement, always back up the relay configuration file using PCM600 (ABB Protection and Control IED Manager).

• Grounding: Ensure the relay casing and the IED’s earthing terminal are properly connected to the substation earthing system to prevent interference and safety hazards.

• Firmware Version: Ensure that the version of the PCM600 software is compatible with the relay’s firmware version to avoid communication or configuration errors.

Product Applications (Typical Use Cases)

The REF615E-G is widely deployed in various medium-voltage power systems:

• Utility Substations: Protection and control of radial, looped, or meshed distribution networks in urban and rural areas.

• Industrial Plants: Feeder protection for manufacturing facilities, refineries, and mines where high reliability is required for process continuity.

• Renewable Energy: Protecting the interconnection feeders between wind/solar farms and the main utility grid.

• Infrastructure: Power distribution for airports, railway stations, and large data centers requiring intelligent power management.
