# Per Unit Analysis for Single and Three-Phase Systems

Learn what Per Unit Analysis is and how manufacturers of electrical equipment use it to rate their equipment. Later, you will use it in your power flow, short circuit evaluation and motor starting studies. 10 lessons in 6h 5min total course length.

## Course Description

In the power systems analysis field of electrical engineering, a per-unit system is the expression of system quantities as fractions of a defined base unit quantity. Calculations are simplified because quantities expressed as per unit do not change when they are referred from one side of a transformer to the other.

In this course, you will learn exactly what Per Unit Analysis is, the main advantages of using it, how manufacturers of electrical equipment use and rate their products, and the technique of converting to and from the Per Unit system. Several examples of working with Per Unit are demonstrated in this crisp clear presentation. When you finish you will have a though understanding of this subject.

It is important for all power engineers and technicians to be familiar with the concept of Per Unit as it is being used and referred to every day in power flow, short circuit evaluation, and motor starting studies.
