why transformer ratings in kva?
Answer Posted / vignesh
Thumb Rule - all AC power sources - Generators,
Transformers, UPS etc. are rated in KVA and all loads are
rated in Watt or Kilowatt..
AND hence there is no need of power factor.
KVA=V X A (FRO SINGLE PHASE TRANSFORMER)
KVA = 1.732 X V XA (FOR THREE PHASE TRANSFORMER)
