The SEL-651RA offers exceptional protection and communications capabilities for 14-pin applications, such as Automatic Network Reconfiguration and controlling distributed energy resource (DER) interconnections. These capabilities assist you in maintaining reliable service to as many customers as possible in the event of a fault.
Quickly commission the SEL-651RA by applying just the settings you need using acSELerator QuickSet SEL-5030 Software Design Templates. Easy-to-use Design Templates create a simplified settings interface and can be customized for your needs. Store templates on the recloser control for quick access when making settings changes. Familiar EZ recloser control settings further simplify and speed commissioning for basic applications.
Customer Outage Minimization—Reduce system and customer impacts by integrating reclosers and controls into your distribution system. You can improve reliability by maintaining service to customers who are not on the faulted segment of the feeder.
Communications-Assisted Protection Schemes—Integrate the SEL-651RA into either Ethernet- or serial based communications networks with standard DNP3 and Modbus protocols or optional IEC 61850. You can use communications for local and remote engineering access, SCADA, real-time protection and control, loop restoration, islanding detection, blocking, and fast bus tripping schemes.
High-Impedance Fault Detection—Detect downed conductors and high-impedance faults with the optional AST. Learn more about this exciting technology.
Distributed Generation Protection—Protect both the utility and the independent power producer with one low-cost device. You can control DER interconnections with IEEE 1547-2018 protection and synchronization and innovative SEL fast islanding detection.
Inrush Detection—Detect transformer energization or motor startup and block tripping for inrush conditions with a second-harmonic blocking element. The harmonic detection element lets you block selected tripping elements until the inrush subsides.
Load Shedding—Use underfrequency and undervoltage elements to implement basic load-shedding schemes. For more advanced loadshedding schemes, rate-of-change-offrequency (ROCOF) elements can shed load for increasing or decreasing frequency.
Synchrophasors Improve Distribution Performance—Apply synchrophasors in distribution applications to identify island conditions.
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 area.
Low-Energy Analog (LEA) Voltage Inputs
Reduce costs and save space with LEA voltage inputs. You can use LEA inputs for three or all six voltage input channels. The SEL-651RA supports many popular reclosers with sensors built right into the recloser bushings (eliminating the need to hang and wire potential transformers to measure the line voltages).
High-Impedance Fault Detection
Detect more high-impedance faults than with traditional protection by using AST.
Additional Inputs and Outputs
Add seven inputs and eight outputs consisting of two 125 Vdc and five 12 V inputs with five Form A outputs and two Form C outputs.
Choose from single-fiber or dual-redundant fiber Ethernet port upgrade options.
Easily integrate the SEL-651RA into your IEC 61850 communications systems.
Upgrade to the 40 Ah extended capacity battery to increase your operation time after a loss of ac power.
Customize your control pushbutton and target LEDs to match your application and workflow with the user-configurable label insert kit.
Program the pushbutton and target LEDs to display as red, amber, or green to meet your application needs and preferences.
