A Delta to Star more practical. Neutral is available on
load side for Line to Neutral voltage.

The Delta on the supply side will filter the undesired 3rd
harmonic.

a delta 2 star transformer s used when there s a need of
neytral for examole industrial lighting. all conversions
depend on your load

Answer / gurucharan singh

Delta star is required only when distrbution system is
required or for higher voltage transmission line to cut
down high power tranformer insulation cost. Delta at
primary is preferred as it does not passes earth fault to
system at delta side. star with neutral is required for
detection earth fault curren, unbalanced loads, single
phase loads...star star or delta delta are considered
normally at same voltage ratio to lower down system fault
current at secondary side.

in three phase with neutral connection, what will happen,if the neutral is in open condition with single phase distribution panel
