I think there is a small mistake in the formula to calculate z_base. You wrote: z_base = 1/y_base = S_base/(u2,ratedu2,rated). However, it should be: z_base = 1/y_base; y_base = S_base/(u2,ratedu2,rated).

Hi @sudo-ac, you are correct. This is indeed a fault. Could you please submit a PR to fix this?
