Course Summary

A fault on a high-voltage three-phase system is simply defined as the number of undesirable, but unavoidable, incidents that can temporarily disturb the stable condition of the power system that occurs when the insulation of that system fails at any point. Moreover, if a conducting object comes in contact with a bare power conductor, a short circuit or fault is said to have occurred. The causes of faults are many, including lighting, wind damage, trees falling across transmission lines, vehicles or aircraft colliding with the transmission towers or poles, birds shorting lines, or vandalism. In this course, the effects of faults on the system will be analyzed.

This course introduces the student to the basic concepts of fault studies on a high voltage three-phase system. Firstly, there is a quick review of “Per Phase” & “Per Unit” methodologies. The student then learns to identify the types of faults on a three-phase system. System faults are then 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 Short Circuit Analysis for HV Systems.

How to get certified?

The rules vary between states, but state boards typically accept a continuing education activity that meets the following criteria: “A course or activity whose purpose and objective are clear with a content that will maintain, improve or expand the skills and knowledge of the licensee’s field of practice.”

Online courses are accepted by all states that require engineering continuing education provided that the student passes a quiz to successfully complete the course, the quiz is graded, and the results are kept on file by the platform for a prescribed length of time (the number of years varies for each state).

 You will be able to immediately print a certificate of completion after passing a multiple-choice quiz.
