Answer / teja

It is not possible unless u provide the input voltage u r going to give for the transformer and how much voltage u want as out put

however if u know input & output voltages primary and secondary current values can be calculated as fallows

2500 KVA 33KV/433V

Then primary current=2500/sqrt3*33=43.745A
And Secondary current=2500/sqrt3*0.433=3333.34A

Answer / abhi

It is not possible unless u provide the input voltage or
current than we calculat
formula
power(2500kva)=Voltage*current

Answer / santhosh

The Question itself is wrong. Only 2500KVA is not enough to
find out the voltage and current values.

Answer / ajar1234

Primary current=2500*1000/1.732*433=3333.52Amps

secondary current= 2500*1000/1.732*33000= 43.73Amps
