Answer Posted / nwachukwu kelechi
The general formula for a 3-phase power transformer is
given by:
power(KVA)=1.732*V*I*pf.
therefore,depending on the pf under consideration, assuming
a unit power factor,500kva power and input voltage of
11000V we have;
current(I1)= 500KVA/(1.732*11000*1)=26.24Amps.
If the output voltage is 400V, the current will then be:
current(I2)= 500KVA/(1.732*400*1)= 721.7Amps.
