# Fault Analysis Using Symmetrical Components in High Voltage Three-Phase Power Systems

Learn the basic concepts of fault studies using symmetrical components on HV three-phase power systems. The final exam and certification are included. 9 lessons in 3h 47min total course length.

## Course Description

This course introduces the student to the basic concepts of fault studies on a high voltage three-phase system. With the help of a quick review of “Per Phase” and “Per Unit” methodologies system faults are analyzed with the use of symmetrical components. System modeling is then used in order to aid in the process, with the ability to move between asymmetrical and symmetrical systems.

At the end of this course, the student will understand the basic concepts of fault studies on a high voltage three-phase system. The student will understand the methodologies of system faults and be able to analyze faults using symmetrical components.

System modeling is then used to aid in the process, with the ability to move between asymmetrical and symmetrical systems.
