Sir
Power transformer :- (in generating station)
Alternator terminals side - Delta
HT transmission line side - Star
Why?
Answer Posted / kc
To reduce the fault level
The fault on primary side ie Y (LLG)
Will reflect as a LL Fault
So fault current level will b less
No zero sequence current ll b appar on d secondary side
