This course deals with the method of symmetrical components, which is used to simplify asymmetrical three-phase voltages and current analysis. The method of symmetrical components converts the unbalanced system into two sets of balanced phasors and a set of single-phase phasors or symmetrical components.  These sets of phasors are called the positive, negative, and zero sequence components. 

An understanding of this method is essential for the understanding of fault analysis and modern-day protection schemes. This course will provide you with the knowledge to comprehend the concept and how it is applied. 

The analysis of power system is much simpler in the domain of symmetrical components, because the resulting equations are mutually linearly independent if the circuit itself is balanced.

Upon completion of this course, participants will be familiar with:

  • Introduction to Symmetrical Components of Three Phase Power System
  • Symmetrical Components Overview
  • Positive, Negative and Zero Sequence Components
  • The “a” Operator
  • Working with the “a” Operator
