Answer Posted / anthony
The inrush current is that value of current used to
overcome the inertia presented by the magnetic dipoles to
the impinging flux . The dipole resists the change in the
turning moment produced by the mag. field ( when machine is
started from rest state).
The jerk current is that value of current that is
drawn in excess of the already supplied current while the
machine is still in operation.
The jerk current is not required to oppose the moment
offered by the magnetic dipole , whereas the inrush current
is used to induce magnetism in a metal and hence overcomes
the dipole moment .
This is the striking diff. between the inrush current
and the jerk current
