Answer Posted / pragati
As compared to a bank of single phase transformers,the main
advantages of a 3 phase transformer is that it occupies less
floor space, less weight,cost is less for about 15% and the
only unit is to be handled and connected.we can save iron.
saving in iron is due to the joint use of magnetic paths
between the coils.
