Per Unit Analysis for Single and Three Phase Systems
"Per Unit Analysis", another tool to help analyze power systems and aid in understanding equipment specifications
Updated on Sep, 2023
Language - English
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 equipment use and rate their products, and the technique of converting to and from the Per Unit system.
Several examples of working Per Unit are demonstrated in this crisp clear presentation. When you finish you will have a thorough 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.
Who this course is for:
- The targeted audience is Managers, Engineers, Technologists, and Maintenance Personnel working in the electrical power protection industry.
What will you learn in this course:
In this course, you will learn exactly what Per Unit Analysis is and how manufacturers of equipment use it to rate their equipment.
What are the prerequisites for this course?
