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

Answer Posted / 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.

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
