Why Transformer in KVA?

Answer Posted / padmanaban

Since Transformer is a Static device and it is having two
losses namely core loss and Cu loss. The core loss depends
on the Voltage (V) only, where Cu loss depends on Current
(I) only.So for this purpose the transformer always called
its rating in apparent power only(VA).
