Why transformer rating in KVA?
and Generator also?
Answer Posted / a.muthukumar, vacon
Cu loss of a transformer depends on current and iron loss on voltage. Hence, total transformer loss depends on volt-ampere (VA) and not on phase angle between voltage and current. It is independent of load power factor. That is why rating of transformer is in KVA and not in KW.
