Power System Theory

This workshop provides participants with the theory of generating an alternating current and the application and effects of resistors, inductors, and capacitors. Also included are the theory, construction, and use of vector diagrams; series, parallel, and series-parallel circuits; power factor calculation and correction; three-phase system theory and application; and the theory and use of transformers in single phase and three-phase systems. Attendees are assigned practical problems to solve during class, with a group discussion of solutions. Following a review of the basic formulae and equations of power electrical engineering, group activities and problem-solving sessions provide overviews for per unit system representation, symmetrical component and fault current calculations, equipment interruption theory and calculations, and transformer capacity calculations.
