Course Catalogue.

After Participating in this course, you will be able to:

• Define Symmetrical Components and their Use
• Understand the Advantages of using Symmetrical Components
• Recognise an Unbalanced System and When it Occurs
• Define the “a” Operator and its Functionality
• Convert to and from Symmetrical Components

Description:
This course is designed to provide a basic understanding of Symmetrical Components used in the analysis of asymmetrical currents and voltages in a three phase system. It will provide the student with the background knowledge on which to model different faults on a three phase circuit. It will include working examples of practical situations and a quick peek into how models are derived for; phase-to-ground, phase-to-phase, phase-to-phase-to-ground and three phase short circuits are derived.

Course Outline:

• Charles Fortescue Engineer and Founder of  Symmetrical Components
• Defining Symmetrical Components
• The Positive, Negative and Zero Sequence Components
• Unbalanced Currents and Voltage in a Three Phase System
• Phase-to-Ground Unbalanced Currents
• Phase-to-Phase Unbalanced Currents
• A Closer Look at the Positive, Negative and Zero Sequence Components
• Defining the “a” Operator and Some of its Properties
• The Process of Converting to and from Symmetrical Components
