Ideally, the neutral point of a 3 phase star connected
generator is zero. As a means of protection of the
generator (stator and rotor windings)the neutral point is
grounded in order that inbalance of voltage between the
phases due to faulty conditions will be sent to ground.This
is to avoid breakdown of stator or rotor windings
insulation, or even severe burn of windings.
