Transmission

COURSE DESCRIPTION

This program is designed to provide an introduction to the basic components that make up a transmission line. The program presents a basic overview of structures, conductors, and insulators commonly found on transmission lines. The program also covers the basic tasks that must be accomplished in order to build a transmission line.

COURSE GOALS
