Not sure what system you ask about.

We have 2 systems in Norway today:

1)A 230/400 V system equal to UK systems.
2)A 230/230 V system where single phase loads are between 2 legs of the 230V 3 phase system. This may or may not have a grounded center of the Y (IT or TT) no Neutral wire at all.

As far as I know this was banned in the UK from 1948.
