there is a # KVA Transformer of 11 KV/440V, in simple(not use formuia) how can you calculate it's HT & LT side current.

Answer Posted / prashant kalivada

KVA = KV x A
= voltage in KV x current in ampere

So, A = KVA / KV at HT side

therefore if KVA is 100 and KV is 11 then
A= 100 / 11
= 9.09 Amps at HT side

and for LT
A = KVA / (V/1000)
= 100 / (440/1000)
= 100 / 0.440
= 227.27 for LT side

Is This Answer Correct ?    6 Yes 10 No
