Main & Complementary
The REF615 is a dedicated feeder IED perfectly aligned for the protection, control, measurement and supervision of utility substations and indust- rial 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 IEDs are characterized by their compactness and withdra- wable design. Engineered from the ground up, the 615 series has been designed to unleash the full potential of the IEC 61850 standard for communi- cation and interoperability of substation automati- on devices.
Unique REF615 ANSI features
• Six setting groups
• Drawout design
• Underground, overhead cable fault detection (CFD)
• High-speed (< 1 ms) outputs
• High impedance (HIZ) fault detection
• Arc flash detection (AFD)
• Thermal overload protection of feeder cable
• Ring-lug terminals for all inputs and outputs
• Large, easy to read LCD screen
• Environmentally friendly design with RoHS compliance
The REF615 provides main protection for over- head lines, cable feeders, and busbar systems of distribution substations. It can be applied for pro- tection 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.
