International distribution systens are fascinating, and completely dispel the myth that Brit is best, too. For example I'm currently in Australia, in basically a Brisbane city suburb. Walking down the road and I realised when glancing at the poles that the same pole is carrying both HV and LV - Conventional delta HV on top and then intermittently it drops down via a TX onto the LV lines and appears as 3PN. Earthing (that I've seen, anyway) is TT. A simple idea that must save on costs massively whilst delivering constancy over long distances.
