This 8 hour class by Jim Phillips, P.E. takes you through the fundamentals of the Per Unit System and Symmetrical Components which are at the heart of power system analysis.
The main purpose of Per Unit is to make the effect of transformer turns ratio mathematically disappear. This greatly simplifies performing electric power system analysis calculations.
Many balanced three phase electrical power system problems can be solved on a per phase basis. This means the calculations are performed for one phase that represents the results on the other two phases.
However, if the system is not balanced such as the case with phase-to-phase and phase-to-ground fault calculations, Symmetrical Components are used. The concept is to solve unbalanced power system problems by resolving the problem into three sets of symmetrically balanced phasors.
Although appearing to be complex, Jim takes you through the fundamentals of each with a series of calculation examples and shows you simplifications that can be made based on his more than four decades of experience.
