Course Description

Goals

To introduce students to

  1. the components of overhead power transmission lines
  2. electromagnetic analysis techniques used to determine the equivalent lumped and distributed parameters for overhead power lines as well as simplified versions of these
  3. electromagnetics analysis techniques used to identify power flow limitations, study the interaction of power lines with other systems, design grounding systems and understand the operation of measurement systems

Learning Objectives

At the end of this course, you will be able to

  1. Understand the reason why different components are used on overhead power lines
  2. Understand the limitations of simple transmission line models usually used to analyze propagation on overhead power lines as well as techniques to extend these models to more general cases as needed
  3. Understand the reason why power flow on high voltage overhead transmission lines is limited as well as techniques used to overcome these limitations
  4. Understand how overhead power lines can and do interact with other systems such as railroad signal systems, pipelines and wireless communication antennas
  5. Understand the principles of electric and magnetic field measurement as well as the limits on any given meter
