A 5 MVA, 6.6 kv Y (star) connected generator has resistance per phase of
0.5 W and synchronous reactance per phase of 2 W. It is protected by a differential
relay which operates when the out of balance current exceeds 30%
of the load current. Determine what proportion of the generator winding is
unprotected if the star point is grounded through a resistor of 6.5 W.
