How to Base Change Per Unit and Percent Impedance Part 2 (Electrical Power PE Exam)
Have you ever noticed that the base change formula for per unit impedance and percent impedance looks backward or incorrect compared to the standard per unit base change formula? In Part 2 of Per Unit and Percent Impedance Base Change we give a real-life example of base changing the percent impedance of a three-phase generator using the ratings of a downstream transformer as the new base values of the system.
