This may sound silly to people in the know, but... in the UK, when they rate a distribution voltage as "11kv" or "33kv" and so on, seeing how the UK only connects phase-phase loads, is this the phase to phase voltage? I believe the low voltage side of the distribution transformers is Wye connected, with delta connected loads.
I once asked my boss when I was being trained as an electrician "what is the phase to earth voltage?". He replied "it's the same as phase to phase at that kind of voltage". It is now my understanding that this could only be true if it was a corner grounded delta system, which aren't used here. So does anyone know?
