Finding the primary VA when winding your own power transformer?
There appears to be a contradiction but you are lacking a vital piece of information; the primary will not have infinite inductance - it will have finite inductance and although this doesn't consume power (unless the core saturates) there will be a VA associated with it in addition to load current VA transferred from secondary to primary.

So the primary consists of load VA and magnetization VA. Typically for a 230 V power transformer (circa 100 VA on secondary), the primary inductance will be upwards of 5 henry and this will have an impedance of 1570 ohms at 50 Hz and will take 230/1570 amps = 150 mA. 

So the magnetization VA is 33.7 VA and total primary VA will be about 134 VA. Not exactly 0.35/0.25 but near enough given that there will be copper losses and leakage inductance losses that I have not accounted for.
