Answer Posted / pritam upadhyay nit p
when secondary is open there ic no flux due to secondary
current to oppose flux due to primary so due to high flux
there is very high voltage induced on secondary side which
causes sparking and damage of core due to high flux demsity.
in case of power transformer flux is constant whtheer
primary open or not so there is no such case as in ct..
