Why the transformer rating is denoted in VA rating why not
in KW
Answer Posted / manish kumar meena
in transformer cu loss depends on current and iron loss on
voltage.Hence total loss depends on volt-ampere(VA) and not
on phase angle between voltage and current.Thats is why
rating of transformer is in KVA.
