Question
how we can know which is Lv side and HV side of transformer
by just seeing it?
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
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.

you can easily find out 1U 1V 1W - This is HT side and 2U
2V 2W this LV side
