Answer Posted / pratik
Since breaker operates in transiant state & it is design to
pass the sub transient current through it.But it is
supposed that if breaker is just about to close & fault
occurs at the same time then breaker will have to close in
that sub transient period & thus amount of arc produce will
be very high.Thus making cap. is very high.
