Advanced Recloser Control
The SEL-651R Advanced Recloser Control offers exceptional protection and communications capabilities for Automatic Network Reconfiguration, three-phase and single-phase tripping, and other distribution automation needs. These capabilities help you maintain reliable service to as many customers as possible in the event of a fault.
Quickly commission the SEL-651R by applying just the settings you need using SEL QuickSet Design Templates. Easy-to-use Design Templates create a simplified settings interface and can be customized for your needs. Store design templates on the recloser control for quick access when making settings changes.
Design Template Guides
Customer Outage Minimization—Reduce system and customer impacts with single-phase tripping and reclosing. Improve reliability by maintaining service to customers who are not on the faulted phase of the feeder. Supported operating modes include: three-phase trip/reclose, three-phase lockout; single-phase trip/reclose, three-phase lockout; single-phase trip/reclose, single-phase lockout; and single-phase trip/reclose, single-phase lockout with three-phase lockout if more than one phase is involved.
Distributed Generation Protection—Protect both the utility and the independent power producer with one low-cost device. Apply directional protection and simultaneously use different protection settings for faults in either direction. Protect the system from voltage angle differences by enabling synchronism check before closing.
Load Shedding—Use underfrequency and undervoltage elements to implement basic load-shedding schemes. For more advanced load-shedding schemes, take advantage of the rate-of-change-of-frequency (ROCOF) elements to shed load for increasing or decreasing frequency.
Communications-Assisted Protection Schemes—Integrate the SEL-651R into either Ethernet- or serial-based communications networks with standard DNP3 and Modbus protocols or optional IEC 61850. Use communications for local and remote engineering access, supervisory control and data acquisition (SCADA), real-time protection and control, loop restoration, islanding detection, blocking, and fast bus tripping schemes.
Inrush Detection—Detect transformer energization or motor startup, and block tripping for inrush conditions with a second-harmonic blocking element. Implement the harmonic detection element to block selected tripping elements until the inrush subsides.
High-Impedance Fault Detection—Detect downed conductors and high-impedance faults with the optional Arc Sense technology. Learn more about this exciting technology.
Fault Location—Combine SEL fault indicators with recloser controls to pinpoint the exact location of a fault, even on lateral feeds—something neither product can do on its own. When a fault occurs, the SEL recloser control reports the distance from the recloser to the fault; however, for lines with branches, the recloser control cannot determine on which branch of the line the fault has occurred. By following the line along the tripped fault indicators, the line crew can easily find the fault a
