Answer Posted / suresh
by calculating the current carrying capacity and the voltage
withstand capacity of the insulation at the time of design
of any new transformer having any current or voltage rating
for previous 11 kv voltage rating the max current current
carrying capacity of wdg conductor at unity powerfactor
which represents KVA eauals voltage and current rating capacity
the eq is kva rating = va rating = V * I * cos @
at unity pf will be 1
