What is the calculating formula for HT and LT amps in a
transformer.

Answer Posted / s.l.bhatt

If the current of one side either primary or secondary is
known than the current of other side will be in same
proportion as the volotage ratio of primary and secondary
side.
For example -for a 1000 KVA 11kv/0.4 kv transformer if there
is 1 amp. current in HT side than current in LT side will be
1x11x1000/400 i.e almost 26 amps.
