Basically a few other similar across spin up tests.

Why voltage at the load their answer required the load 480V divided by 1.73 then multiply by 1.73?

I thought you only need divide by 1.73

My solution:

Z = 0.5+j0.08 (750/1000) = 0.38 <9.1

Vt= 480/1.73 - (100<-36.9)(0.38<9.1)

= 244V

Their answer is 422V

Is it because it's a 3 phase load?
