The Per Unit System
Lesson 3 of 40 • 71 upvotes • 13:38mins
Nikhil Nakka
A large interconnected power system has various voltage levels (due to transformers) and various capacity equipments. Therefore it convenient to work with per unit (p.u.) system of quantities for analysis purposes rather than in absolute values of quantities. The concepts of the per unit system are discussed in this lesson.
