Answer / sheik

to measuring in full load

Answer / bala

fully depends on the demand load in that power transformer
install area

Answer / suresh

by calculating the current carrying capacity and the voltage
withstand capacity of the insulation at the time of design
of any new transformer having any current or voltage rating

for previous 11 kv voltage rating the max current current
carrying capacity of wdg conductor at unity powerfactor
which represents KVA eauals voltage and current rating capacity

the eq is kva rating = va rating = V * I * cos @

at unity pf will be 1

Answer / thanigai1984

by measuring the capacity of transformer..

Answer / sanjay kumar behera

We know that the KVA rating of transformer always depends on the loss of that transformer.So for core loss calculation we can apply the open circuit test method as the core loss depends on voltage and for the calculation of copper loss we can apply the short circuit test method in which the copper loss depends on the current.

Since phi is the angular displacement between V & I, then why we use phi in power triangle ie. when showing active, reactive & apperent power in triangular manner & if it is ok then where is V & I in the triangle.
