TST 101: SEL Relay Testing Basics
Description
TST 101 provides a beginner-level introduction to testing SEL relays. Students will learn basic relay testing skills; acquire skills required to work with SEL relays, such as using Relay Word bits and relay event reports; and practice acquired skills by working with a phase and ground distance (SEL-311C) relay during the training.
Audience
This course is intended for relay technicians or protection engineers and system consultants with an interest in relay testing.

Learning Outcomes
At the conclusion of this course, students can:
- Establish a serial communications link with an SEL relay using SEL software.
- Enter settings into an SEL relay.
- Equate Relay Word bits and SELogic control equations to traditional relay element outputs and discrete contact logic.
- Test, commission, and troubleshoot using metering, sequential events recording, and event reporting features of SEL relays.
- Analyze information recorded by the relay using SEL software.
- Calculate relay test points to verify responses.
- Find information in the SEL relay instruction manuals.
