Answer Posted / anoop
isolation transformer is having same no. of turns in
primary and secondary side as rightly said by one of our
friends. its main purpose is used to isolate/remove the dc
components from ac, as transformer cannot transform dc from
one circuit to another because there will not be any rate
of change of flux associated with dc. so sewcondary side
Kva will be dc component free.
