TST 107: SEL Transmission Substation Relay Testing

Description

TST 107
Course Information

This is a three-day course.

Course Base Fees: $1,500 USD

TST 107 covers skills required to enter settings, test, commission, and troubleshoot this class of SEL relays. Students will:

  • Review skills required to work with SEL relays.
  • Learn about specific transmission relay testing considerations.
  • Practice skills through 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.

SEL equipment will be used during the training, including transformer protection (SEL-487E), distance and directional (SEL-421), and advanced line current differential (SEL-411L) relays.

Audience

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