Analyzing Asymmetrical Three Phase Power
Created byGraham Van Brunt P. Eng., B.Sc.
Last updated 6/2020
English

What you'll learn

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

Description

This Course “Short Circuit Analysis for HV Three Phase Systems” 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” & “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.

Who this course is for:

  • The targeted audience is Managers, Engineers, Technologists, Maintenance Personnel working in the electrical power protection industry.
