Answer / nithi

for a distribution transformer(22 kv or 11kv/440v),there is
a bushing in the HV side whereas LV side doesn't has.
in a small transformer (used in radio,tv....),the
size of the lv side winding (conductor size)is slightly
bigger than the HV side winding.

Also,HV winding is always wounded over the LV
winding.

Answer / m.saravanakumar

The LV side mostly STAR winding, That's why which has four Bushings that is R, Y, B phases and neutral. But in HV side mostly Delta winding that's why which has three bushings.

Answer / mubasher

Try to see the connected cables if you can distinguish between HV & LV cables
HV side there is only one big cable which is multi core and LV side three separate cables and neutral cable
if there are no connected cables then see the glands available for cables; at LV side there is provision of single gland and at LV side there is LV cables termination box.
