This is a three-day course.
Course Base Fees: $1,500 USD
In this course, you will learn the skills required to enter settings, test, commission, and troubleshoot SEL relays. You 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 feeder protection (SEL-751A), transformer protection (SEL-787), and directional overcurrent (SEL-351S) relays.
TST 103 is intended for relay technicians or protection engineers and system consultants with an interest in relay testing.
