how to calculate busbar capacity for 1000Kva transformer having22/.433V..

Answer / shaik

First of all the voltage ratings given in the question might
be wrong. But the basic rule for calc. the ampacity is to
first find out the current..

Power/ Volts = Amp.

Then the ampacity of the conductor is choosen by taking 125%
of the current.

Here if i consider voltage of this tranformer to be 22/.433
kv. then on primary side the busbar capacity has to be,

1000x1000/22x1000 =45.45 A

45.45x 1.25=56.81 Amps.

Therefore the busbar capacity on primary side should not be
less than 60 Amps.

Similarly, secondary side is calc.
