TST 103: SEL Feeder Relay Testing

Overview

This course is intended for relay technicians or protection engineers and system consultants with an interest in relay testing.

In TST 103, students will learn the skills required to enter settings, test, commission, and troubleshoot SEL relays.

Students will:

  • Review skills required to work with SEL relays
  • Learn about specific distribution relay testing considerations
  • Practice the acquired skills by working with different relays throughout the course
  • Gain familiarity with the operating principles of each type of relay
  • Explore the features of SEL relay technology to make appropriate choices when designing test routines

A variety of SEL relays are used during TST 103, including overcurrent (SEL-551), directional overcurrent (SEL-351S), and percentage-restrained differential relays (SEL-587).
