why transformer ratinh is in KVA????/ ..

Answer / arun.giit

as all the losses is in the form of power;and in transformer
iron loss is directly propertional to voltage(V) &copper
loss is propertional to current(I).it is not depend upon
powerfactor,so it's rating is in KVA.

why transformer ratinh is in KVA????/ ..

Answer / shaikh

Cu loss of transformer depends upon current I and iron loos
depends upon voltage V...So as we can say that the total
losses of the transformer depend upon VA (volt-ampere) and
independent of phase angle between V & I (i.e. pf
angle)...so transformer rating is in kVA & nt in KW...

why transformer ratinh is in KVA????/ ..

Answer / tin`

Becuase kVA is the 'total' apparent power. The load
connected to the transformer can have different power factor
(pf) and so the kW rating will vary according; kW=kVA*pf.
The transformer rating is stated in kVA in order to show
the full capacity of the transformer and then the real
power (kW) rating can vary with power factor.

why transformer ratinh is in KVA????/ ..

Answer / salim

bcz
kw=kva×pf and load on tranz.is not constant.So pf is varies with load.thats why traz.rating is always in kva not in kw

why transformer ratinh is in KVA????/ ..

Answer / mohan singh

Transformer ratings are in KVA because the power factor is
for the load on which transformer will operate is not known
in manufacturing and KW = V x I x Cos Phi.so it is Rated in
KVA and not in KW.

why transformer ratinh is in KVA????/ ..

Answer / peter

coz KW or HP makes no sense.....transformer is not a power
conerter involving mechanical energy.....i mean...it just
transfers electrical energy ....

why transformer ratinh is in KVA????/ ..

Answer / bob

Because transformer is power source and active power and
reactive power drawn from it depend on load nutural.
