The reason behind my question is that i am looking into specifying a transformer which happens to be 11kV/433V. I understand that the normal LV voltage for the UK is 400/230. So i am looking into shifting the taps.
433V at the transformer probably isn't unusual for a UK setup. The UK supply standard is nominal within a -6% to +10% range - i.e. between 216.2V and 253V L-N.
433V L-L comes it at about 250V L-N and so is within the acceptable UK range - and allows for some voltage drop in the LV supply lines (which may or may not be useful depending on how far from the transformer your loads are).
