PROT 407: Transmission Line Protection

Overview

Engineers and power system consultants who need a comprehensive understanding of the challenges and solutions for protecting high-voltage power transmission lines should attend this course.

PROT 407 provides an in-depth study of the methods used in designing protection systems for high-voltage power transmission lines. The course provides advanced guidelines for relay application and settings for transmission lines, including series-compensated lines. It also reviews time-domain ultra-high-speed line protection principles. The course covers the application and settings of power swing blocking and out-of-step tripping functions.
