As we know,capacity of conductor carrying conductor is
fixed in a perticular atmospheric conditions.Current in
transformer or DG set or alternators depends on load power
factor, current drawn by a perticular KW machine is more if
power factor is low whereas same KW rating machine wil draw
less current if it has high power factor.Hence
Transformer/DG/Alternator can not be designed for KW but
for KVA rating.It will feed high KW with high power factor
and low KW with low power factor without damaging winding
conductor/insulatin.
