1:--- actually we used delta -star connection in power
distribution transformer to provide the returning path of
current,because connected load does not balanced so
returning current goes to transformer star point through
neutral wire which always earthed.
2;---In distribution load is being different type like
single phase three phase etc so we have required neutral for
single
phase load which is only possible in star connection.

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
