APP T400L: SEL-T400L Time-Domain Line Protection

Description

SELU
Course Information

This is a three-day course.

Course Base Fees: $1,500 USD

APP T400L covers traveling-wave protection concepts with hands-on application where you will learn about the SEL-T400L Time-Domain Line Protection relay’s protection and fault-locating functions. You will also complete hands-on exercises to configure, set, and test the relay.

Audience

This course is intended for utility transmission protection engineers, electrical technicians, and power system consultants who want to understand the protection principles, logic, and testing of the new SEL-T400L in detail.
