ABB RED615 IEC Line Differential Protection Relay

ABB RED615 IEC Line Differential Protection Relay Overview

The ABB RED615 is a phase-segregated, two-end line differential protection and control relay engineered for the protection, control, measurement, and supervision of overhead line and cable feeders. Part of ABB's Relion® 615 protection and control series, the RED615 operates within IEC-standard frameworks and serves utility and industrial power distribution networks, including radial, looped, and meshed configurations with or without distributed generation.

Key Features

• Phase-segregated two-end line differential unit protection supporting both sensors and conventional instrument transformers
• Ready-made IEC-compliant standard configurations with fast commissioning and tailoring capabilities
• Withdrawable plug-in unit design enabling swift installation and testing
• Large graphical display showing customizable single-line diagrams (SLDs), accessible locally or via web-browser-based HMI
• Inter-substation communication through fiber-optic link or galvanic pilot wire connection
• Support for line differential applications with an in-zone transformer
• Manufactured by ABB Oy Distribution Automation

Practical Applications and Operational Use

The ABB RED615 protection relay is deployed in substations where selective, high-speed unit protection of feeders is critical. It safeguards overhead lines and cable feeders against phase-to-phase and phase-to-earth faults by continuously comparing currents measured at both ends of the protected zone. Operators deploy it across utility distribution networks and industrial power systems that include distributed energy resources, including radial, looped, and meshed topologies.

The relay's dual communication options, fiber-optic link or galvanic pilot wire, allow flexible deployment across varied substation infrastructure, including retrofits on existing pilot wire circuits. Engineers can monitor status and configure parameters through the integrated web-browser-based HMI without dedicated vendor software.
