Answer / vinod

for 3 phase balance phase voltage, earth fault detection
and humen/equipment safety

Answer / kavi

Fcuk damnit, distribution transformer earthing is required
to provide a zero reference for single phase loads, assuming
TT distribution. It balances the phase currents. Balanced
loads rarely exists on distn trx. Also, the third harmonic
current generated due to magnetisation of the core will be
grounded.
Power tx require grounding for the latter purpose and for
insulation reasons. more economical to fabricate a tx with
phase voltage insulation than delta.

Answer / ayid

for balancing purpose and safety particularly 3phase tx

Answer / chinmaya

Earthing is required for grounding the excess current.

Answer / sarvesh singh

earthing is done as to complete the circuit. Else it could
also be connected to a neutral wire. In many houses there
is one wire connection i.e. live wire and for the neutral
we use as a ground. in transformer in primary there could
be some current in neutral wire so we need earhing so as to
have proper output voltage

can we transmit power with out cable if it is possible how it is possible.
