Why the substation measure in KV but not in the power ratings of transformer.
Answer Posted / j.prakash
Transformer is static device there is no any rotating part
so there is no any friction losses, only iron loss and cu
loss in transformer, iron loss depend upon the voltage and
cu loss depend upon the current, there in no any loss which
depend upon power factor,so rating of transformer only in
kva.SO NOT IN KW..
