Things takes time, the building process is not finished yet, and the cable are still running trough the house. :-)

They has had proffesionals there now, and the cables are now propery put in the ground with the right kind of cable, and terminations.

I am wondering how they will do it, but someone was telling me that they want to convert the area from 230V TT to 400/230 TNC-S

My guess will be a transformer with both voltages, and dirstibution of of the 400V system to new houses.

They could convert the existing buildings too, it'd take new cables and some inside work too. I guess a dual-voltage transformer wouldn't be enough for running both systems in parallel since the old setup requires a floating star point (IT) while the new one needs an earthed one (TN).

The old system is a TT system so it will probably be OK, In the neighborhood they even have a transformer with 2 separate secondary winding's too.

I suppose they could convert the older parts to 133/230 V TT if they're currently 133/230 IT with earthed local PE. That'd be the Belgian system, once common in quite a few European countries. They'd still need a transformer with separate secondaries I guess. If all existing supplies are single phase (i.e. only two out of the three phases are supplied, giving 230 V) they could replace the distribution and reconnect the existing buildings to 230 V line to neutral instead.

It is already 133/230 TT, so I guess that is the way they will do it.
