Answer Posted / jagadisha
The vector group is used to know the type of winding in
Transformer.First letter in the vector group indicates
primary winding(neutral is indicated if present) and the
second letter indicate secondary winding and next letter is
indicate phase difference between primary and secondary..
let us consider vector group Dyn11-It is most coomon 3-PH
connection,ie Delta is on primary and Star on sec with phase
displacement of 30deg

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened.
