Symmetrical component questions can be tough! Especially with per unit values.
I'm happy to share a new free article with a video demonstration showing how to solve a PE exam like practice problem with a full worked out solution, step by step.
Here's the practice problem. For the solution, click on the link to the article directly underneath it.
Symmetrical Components Single Line to Ground Fault Example Problem:
"A single line to ground fault occurs somewhere along the 50 mile transmission line connecting the utility substation bus #1 to transmission bus A. Using the transmission line diagram, solve for the fault current magnitude in amps at this point if the zero sequence impedance is 0.241pu, and the positive and negative sequence impedances are both equal to five times the zero sequence impedance. Use the generator power rating and the system voltage at the fault as base values."
Can you solve it?

As always, I'm happy to offer help and answer any questions.
Enjoy!
