Answer Posted / rk
As mentioned earth and ground are the same terms used in
different countries. The earth (ground) conductor is
electrically connected to the earth so that anything it is
connected to, cannot become live. There will be be some kind
of local regulation determining the maximum resistance that
is allowed where the connection is made to ground (rod, mat etc)
The neutral is one connection of the supply transformer that
is also connected to earth. It is not a return path as such
because ac is changing direction. The reason it is connected
to earth is for safety. It means that a fault (to earth) of
the live conductor will cause the overcurrent device (fuse
or breaker) to operate and trip the power.
There are systems that do not connect one side of the supply
transformer to earth (no neutral). They still function just
the same as an earthed system. This is more common in
military or medical and requires some form of sensing
circuit to detect faults but the fault gives an alarm rather
than a trip so that power remains until an outage can be
planned to find the fault.
