The method of symmetrical components is used to simplify asymmetrical three-phase voltages and current analysis by converting the unbalanced system into two sets of balanced phases and a set of single-phase phases, or symmetrical components. These sets of phases 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 exactly 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 currents and understand fault analysis.
Including Positive, Negative, and Zero Sequence Components.
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".
The student should have an understanding of the laws and theorems related to three-phase electrical power systems.
