In Stock: 2description
ABB REF615 Relay, ABB REF615 ANSI Feeder Protection relay: A compact and versatile solution for utility and industrial power distribution systems. ABB REF615 Relay is a dedicated feeder protection and control relay for protection, control, measurement, and supervision of overhead lines and cable feeders in utility and industrial power distribution systems, including radial, looped and meshed distribution networks, with or without distributed power generation.
The REF615 is a dedicated feeder relay perfectly aligned for the protection, control, measurement, and supervision of utility substations and industrial power systems.
REF615 is a member of ABB’s Relion family and a part of its 615 protection and control product series. The 615 series ANSI are characterized by their compactness and withdrawable design. Engineered from the ground up, the 615 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability of substation automation devices.
ABB REF615 Numerical Relay
Scope
- Feeder protection
REF615 Numerical Relay Application
The REF615 provides main protection for overhead lines, cable feeders, and busbar systems of distribution substations. It can be applied for the protection and control of grounded and ungrounded distribution systems. Flexible order coding allows for choosing current-only or current-and-voltage configurations to best fit your distribution feeder application needs.

Protection and control
Protection and control
The REF615 is the most powerful, advanced, and simplest feeder protection relay in its class, perfectly offering time and instantaneous overcurrent, negative sequence overcurrent, phase discontinuity, breaker failure, thermal overload, and voltage metering and protection. The relay also features optional high impedance fault (HIZ) protection for grounded and ungrounded distribution systems. Also, the relay incorporates a flexible three-phase multi-shot auto-reclose
