Why we should use delta connection in primary and star
connection in an distribution transformer, which converts
400v a.c. voltage to 33kv.
Answer Posted / pankaj malhotra
For distribution transformers, loads are connected to
secondry side. hence, requirement of neutral can be
obtained by connecting secondry of the transformer in star.
Secondly, to reduce or minimise the third harmonics in the
transformers, primary side connection generally done in
delta.
