Sir
Power transformer :- (in generating station)
Alternator terminals side - Delta
HT transmission line side - Star
Why?

Answer Posted / nagarajan

Example 15mva,220/132kv
Star 220kv here phase voltage =line volatge/1.732=127kv
delta 11kv here phase voltage =line volatge.
Because star side we have neutral ,a.insulation cost less and 127kv insulation is sufficient but in this delta we require 132kv insulation.

Is This Answer Correct ?    0 Yes 0 No
