This document outlines a session plan for teaching about the performance of short transmission lines. The session will begin with taking attendance and reviewing the previous lesson. Students will learn to differentiate between short, medium, and long transmission lines and understand ABCD parameters for transmission lines. The content will include basics of transmission lines, classifying lines by length, and analyzing the performance of single and three-phase short transmission lines through demonstrations and examples on the board. Students will complete a quiz to evaluate their understanding of topics like voltage regulation and efficiency. For next session, they will prepare to learn more about transmission line parameters.

6. Basics to Transmission lines
• Transmission lines are normally operated with a balanced three phase
load therefore the analysis can be done on per phase basis.
• A Transmission line on a per phase basis cane be regarded as a two port
network, wherein the sending end voltage Vs and current Is are related to
the receiving end voltage VR and current IR through ABCD constants.
