Answer / fahad

bcoz the power factor of load is not known during the
manufacturing, this is also done during load calculation.
For reference you can see a indian book " B.L Theraja -
Electrical Technology" ....

Answer / amit

bcoz iron losses depdens on voltage and copper losses
depends on current that's why transformer rated in KVA

Answer / thanigai1984

Transformer is not consider the power factor so its
capacity is in KVA

Answer / mathivanan k

the pf will be indipendent to the trf,the pf only act at
load equipment side only
so the trf is not load
and it's losses depending copper&coreloss then only it is
mention in VA it is bulk amount so KVA

Answer / mintu kr. pandit

Mainly reason for no-load current consumption of transformer in losses hysteresis loss and eddy current loss.

Answer / realas

Because the flowing of current in secondary winding is
without/no losses so the apparent power is zero. Hence, the
transformer may call either by KVA or KW since it is equal.

Answer / sachin verma

BECAUSE VOLATGE IS measured in volts and current in ampere.

Answer / ravindranath

transformer of is close to one that is why it is not expressed in kw
