In-person instruction

Industrial power systems analysis I

Learning objective

Upon completion of this course, attendees will be able to recognize the several forms of power system single-line diagrams, calculate short-circuit current, and evaluate the application of power circuit breakers and power fuses.

Course abstract

Using classroom exercises and demonstrations, this training program reviews the fundamental techniques of power systems analysis. Although it is not intended to teach the use of power systems analysis software, the instructors will use laptop computers in the classroom and review examples to help explain the construction of system single-line diagrams and the calculation of short-circuit current.

Target audience

Power system engineers, field service engineers, application engineers, sales engineers, technicians and others who want a solid understanding of short circuit analysis.
