This course is designed for utility and industrial protection engineers and power system consultants.
APP 351R: SEL-351R Recloser Control
Students will explore the traditional recloser control functions and the complete distribution system protection capabilities of the SEL‑351R Recloser Control. The course also covers advanced applications, including selective load shedding, loop-feed systems, and using dual recloser controls to provide premium service reliability.
APP 651R: SEL-651R Advanced Recloser Control
This course provides an introduction to the SEL-651R Advanced Recloser Control. The course also covers basic recloser control functions, advanced capabilities, and application examples, including Automatic Network Reconfiguration, single-phase trip and reclose, and harmonic analysis. The course also includes an introduction to the acSELerator QuickSet Design Templates for creating customized settings templates.
Students (in groups of two) will work directly with the SEL-351R and SEL-651R Recloser Controls, performing hands-on communications, settings, and testing.
