POLYTRANZ transformers convert three phase power to single phase, ie 415volt three phase to 240volt single phase.
For example if you require to operate a number of single phase loads from a three phase source (ie: a three phase generator) and you wish to draw this from each phase this is not always possible, with a POLYTRANZ transformer the single phase output current draw is spread across each three phase leg of the three phase input supply.
