But the main question about transformer rating is why transformer power rating in KVA this is the unit of electric power which is actually called apparent power.
There are three types of electrical power active power (KW) apparent power (KVA) and reactive power (KVAR).

So in this video I explained completely why transformer rating in kva in hindi language or why transformer rated in kva instead of kw. There are too many transformer types and in any transformer two basic losses occurs copper losses and iron losses (core losses) so what is the mystery behind this?
In this tutorial I show some three phase transformer which are basically step down transformers and pole mounted transformers and I tried to brief kva transformer basic kva calculation and mathematically proved transformer rating kva why and transformer rating in kva not in kw.
