Per Unit and Symmetrical Components – Electrical Power Calculations

May 7, 2015 @ 8:00 am - August 5, 2015 @ 5:00 pm

Per Unit and Symmetrical Components
Electrical Power Calculations

his course by Jim Phillips, P.E. has become the industry standard that defines the “Crash Course” in electrical power system analysis. Very few universities teach Per Unit and Symmetrical Components calculations anymore but it is still a fundamental concept for electric power system analysis. Jim Phillips teaches you the basics of the per unit system and electric power system analysis during the first day of the two day class.

On the second day, Jim builds upon the per unit system and takes you to the next level with symmetrical components and unbalanced power system calculations. Learn how to more easily use positive, negative and zero sequence components and draw zero sequence diagrams.This class is loaded with many in class examples and problems for a hands on learning experience.

Jim has developed this course based on over 30 years of extensive experience with industrial, commercial and utility power systems.

What You Will Receive

• Training manuals of 5 modules containing almost 500 pages
• Jim’s short circuit calculation worksheets
• Harmonic analysis and design worksheets
• Access to Technical articles
• Many calculation examples and problems
• 32 hours of Continuing Education Credit
