this is simple .. assume a 100kva tr, ok
then p= vi ( power = voltage x current)
1.lets see for HT side
p( kva)= root 3 ( for 3 phase)x voltagex current
=> kva = root3xvxI
=> 100kva=1.732x11kvxI
=> I= 5.25amp/phase
2. similarly in secondary side means LT side
=> 100kva=1.732x440xI
=> I= 144amp/phase
