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.
