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.
