what is inrush current in transformer?
Answer Posted / chetan & panks
When we charge the Trafo, flux will get generated there,
but when we make get it isolated some flux will remain
there.
Again while we charge the trafo,remaining flux will oppose
the present flux hence high current will get generated,
which is very dangerous for trafo. The current produced as
in above condition is called Inrush Current, which is
flowing for very minor time (i.e. for 4-5 secs)
