APP 351R: SEL-351R Recloser Control

Overview

This course is designed for utility and industrial protection engineers and power system consultants.

Students in APP 351R explore the traditional recloser control functions and the complete distribution system protection capabilities of the SEL-351R Recloser Control. APP 351R also covers advanced applications, including selective load shedding, loop-feed systems, and using dual recloser controls to provide premium service reliability. In groups of two, students will work with the SEL-351R to perform hands-on communications, settings, and testing.

Course Objectives

At the conclusion of this course, students can:

  • Describe how to upgrade existing substation and pole-mounted recloser controls
  • Communicate with the recloser control through front-panel and serial port interfaces
  • Use acSELerator QuickSet SEL-5030 Software to apply EZ settings, program SELogic control equations, and analyze event reports
  • Discuss relay-to-relay logic communications via the Mirrored Bits communications protocol
  • Coordinate with upstream feeder relays for high-speed fault clearing on distribution circuits
  • Apply high-side transformer blown fuse detection logic to protect customers from potentially damaging unbalanced voltages
  • Use the fault detection capability to identify feeder trouble points
