what happens when dc supply is given to the transformer?..

Answer / jadhav babu

if we give dc supply to the transformer the primary side
winding will get induced emf which is constant ,but we
require an variable emf so that mutual induction takes place
and emf is induced in secondary of the transformer .if dc is
given for a longer period the transformer may get damaged

Why we transmit the power at the voltage in the multiple of 11 or 1.1 like 11kv, 22kv, 66kv, 132kv...... some one told me that it is due to fomr factor 1.1 of sine wave. its fine but while transforming we can choose any voltage, so why only multiple of 1.1 there also.......? plz tell me.
