Product Introduction
ABB REV615 is a numerical generator protection and control relay developed for utility power plants, industrial generation systems, combined heat and power (CHP) facilities, and renewable energy applications requiring dependable generator protection and advanced substation communication capability.
As part of ABB’s Relion® 615 series, REV615 integrates generator protection, monitoring, control, event recording, and IEC 61850 communication functions into a compact withdrawable IED platform suitable for both new generator installations and retrofit modernization projects.
The relay provides comprehensive protection for synchronous and asynchronous generators, including generator differential protection, stator earth fault protection, reverse power protection, over/under frequency supervision, and synchronism check functionality. Compared with older electromechanical or early numerical generator relays, REV615 improves fault analysis capability, interoperability, communication flexibility, and engineering efficiency.
Its IEC 61850 support, configurable logic, and disturbance recording functions make it suitable for modern digital substations and distributed generation systems. Exact firmware revision, communication configuration, and application package should always be verified before commissioning or retrofit replacement.
