Hello, I thought passing FE, PE exams would be the hardest thing in the journey of becoming a PE. However, it seems like I am stuck with the credential evaluation since I will need additional 4hr credit to get my Illinois Stamp. I could either fly out and challenge CLEP chemistry (6 credit exam)...

Thanks for your detailed explanation.

Much appreciated @Zach Stone P.E. I am still wondering why the per unit equation cannot be used here.

Hello, I am kind of confused after seeing two equations that usually we encounter in circuit analysis. It has been noticed that the secondary impedance can be referred to primary by multiplying it with the square of the transformation ratio. However, if we utilize the formula to change per unit...

Thanks, Zach. Much appreciated

Please advise if I am wrong with the Zpu calculation. NCEES solution used Generator X'd as Generator Impedance (without considering resistance). Attached are the question and the workout

It does not really matter which MVA rating is considered as the base. If you are choosing Gen rating as a base, then you will need to convert the impedance to the new base when transferring to the 460V side. Since Primary voltage is not given in the question, the conversion seems impossible, and...

I thought a pictorial representation may be helpful to understand each step involved in this calculation. I
