Answer Posted / 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.
