Major factor is insulation of winding of transformer because
at the LV side it will nearer to the core or inside section
and HV is wound at the outer section of core or upper on LV
winding side. If we put tape changer at LV it is very
difficult to get there winding at outer portion (it will
effect on maintenance or manf point of view).
Other factor is if we change voltage at LV SIDE it should be
change very little as per requirement SO we will connect
tape changer at HV side for constant or stable voltage.

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.
