It\u2019s important to practice these techniques in order to fully understand and feel comfortable with them.<\/p>\n<p>This course provides both\u00a0<strong>theoretical and real-world examples<\/strong>\u00a0with questions that can be used to gain experience with symmetrical components. You will learn about faults due to the wrong operation in the power system.<\/p>\n<p>There are two major problems that can occur in electrical systems: these are\u00a0<strong>open circuits and short circuits<\/strong>. Of the two, the latter is the most dangerous because it can lead to very high fault currents and these currents can have very substantial effects (thermal heating and electromechanical forces) on equipment that may require replacement of equipment and may even cause fires and other similar ensuing effects in the electrical system.<\/p>\n<p><iframe src=\"https:\/\/player.vimeo.com\/video\/625255912?dnt=1&amp;app_id=122963\" width=\"640\" height=\"360\" frameborder=\"0\" allow=\"autoplay; fullscreen; picture-in-picture; clipboard-write\"><\/iframe><\/p>\n<p>To prevent problems from short circuits, it is necessary to design electrical protection systems that will be able to detect abnormal fault currents that may occur and then take remedial action\u00a0<strong>to isolate the faulty section of the system<\/strong>\u00a0in as short a time as is consistent with the magnitude of the short circuit fault current level.<\/p>\n<div class=\"info_box\">This requires that the fault current be predicted for a fault in any particular location of the circuit system. We thus need <strong>to establish methods of fault calculation<\/strong>.<\/div>\n<p><strong>You will learn in this course:<\/strong><\/p>\n<ul>\n<li>Meaning of a fault in the electrical
