In single phase system, nothing will happen. If there is any
higher current flowing and any short circuit occurs neutral
fuse will blown off if it is weaker than fuse in phase and
hence electrical apparatus will not work.
But in 3 phase system, we should not provide fuse in neutral
link, why because, even if we divide the loads equally in
three phases, some time, some of the loads may be switched
off. At that time load will not be balanced. During that
time neutral fuse blows off if any reason, phase voltage
will be increased where the load is less compare to the
other phases which causes electrical apparatus in that phase
will burn.

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
