Symmetrical Components for Three Phase Power Analysis

Course Summary

The method of symmetrical components is used to simplify asymmetrical three-phase voltages and current by converting 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.

In this course, you will learn what symmetrical components are, their main advantages, and how manufacturers of equipment use them. You will learn how to use symmetrical components to simplify asymmetrical three-phase voltages and current and understand fault analysis. In the case of three-phase systems, the resulting “symmetrical” components are referred to as direct (or positive), inverse (or negative), and zero (or homopolar). The analysis of power systems is much simpler in the domain of symmetrical components because the resulting equations are mutually linearly independent if the circuit itself is balanced.

You can later apply this knowledge to single-phase to ground, two-phase to ground, phase-to-phase, and three-phase fault conditions. This course may be considered a prerequisite to the course “Short Circuit Analysis for High-Voltage Three-Phase Systems.”

How to get certified?

The rules vary between states, but state boards typically accept a continuing education activity that meets the following criteria: “A course or activity whose purpose and objective are clear with a content that will maintain, improve or expand the skills and knowledge of the licensee’s field of practice.” Online courses are accepted by all states that require engineering continuing education provided that the student passes a quiz to successfully complete the course, the quiz is graded, and the results are kept on file by the platform provider for a prescribed length of time (the number of years varies for each state).

Automatic certificate of completion can be generated after completing the course.

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz.
