Transformer Rating in KVA not in KW:
As We know Two type of losses in
Transformers:-
- Cu Loss (Copper Loss)
- Iron Loss
Cu loss of transformer depends on Current
and Iron Loss of Transformer Depends on Voltage. So, Total Transformer loss
depends on Voltage-Ampere and not on phase angle between voltage and current
i.e. it is independent of total power factor (pf).
For that kind of reason Transformer
Rating is in KVA ( Kilo Volt Ampere ) and not in KW (kilo watt).
Great
