In a 3 phase system the usual way of connecting the
transformer is in star to have a neutral. The current
flowing in the neutral does not flow to earth but to the
star point. The star point is the opposite end of the
windings where the phase is connected and the 3 are joined
together. The current in a balanced 3 phase system for
example a 3 phase motor flows through the phase wires and
not the neutral. An unbalance would be where something is
connected to a single phase and the neutral. This would be
lights for example. Here the current flows from the phase
and back through the neutral.
