I have a basic question about transformer ratios, if I have 3 windings, a pri, a sec and an aux, what's the voltage expression for each winding? My guess is
Vpri = Npri/Nsec
Vsec = Nsec/Npri
Vaux = Naux/Npri
is this right?
thanx!

I think you need to consider the voltages as well as the primaries. That is:
Vsec = Vpri * Nsec/Npri
That sort of thing. I don't think you normally calculate Vpri; I think it's what you choose (within limits of the transformer, of course). Then you use Vpri to calculate the other voltages, based on the winding ratios to Npri.
It seems to me that Vaux would be:
Vaux = Vpri * Naux/Npri
-- Stenderup's Law: The sooner you fall behind, the more time you will have to catch
V_pri/N_pri = V_sec/N_sec = V_aux/N_aux

sorry I forgot to include the voltages, I meant
Vpri =3D Vsec*Npri/Nsec
Vsec =3D Vpri*Nsec/Npri
Vaux =3D Vpri*Naux/Npri
which seems right after reading the responses, thanks
