For substations, ABB, a power and automation technology group, announced the release of its Relion® REF615R feeder IED. The REF615R was designed to offer an easy, quick and affordable way to upgrade ABB¹s DPU2000R relay along with providing a 19-inch rack mount version of the REF615 feeder IED.
The REF615R is a member of the ABB Relion product family and part of its 615 protection and control series. 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. The new product contains the functionality of traditional REF615, as well as features utilizing some of the latest technologies available today.
“The 3U 19-inch rack mount ensures a seamless, effective way to upgrade the DPU2000R,” said Kevin Koder, marketing director, ABB Distribution Automation. “The same form and fit plus the wire-alike feature provide significant cost savings and greatly reduced installation time. This gives REF615R users a simple, economical solution for upgrading to current technologies.”
There are four major ease-of-replacement benefits for ANSI and IEC DPU2000R users:
• Same form and fit eliminates panel cutting or rack repositioning
• Wire-alike I/O and CT/VT connections greatly reduce drawing modification time
• Comparable protection and control plus more included
• Near SCADA-alike for DNP3.0 points and Modbus registers
The REF615R feeder protection and control relay offers non-directional and directional phase and ground overcurrent, voltage and frequency protection, flexible multi-shot auto-reclose control, synch check, power system metering, advanced local human machine interface (LHMI) and embedded web-server for ease of data retrieval and setting. The relay also offers optional sensitive earth fault (SEF) protection, power quality, arc flash detection and cable fault detection (CFD) for detecting incipient cable faults.
