First to calculate current, we should know the PF of
load... without knowing the load we can't tell load
current.........
Formulais I = KVA / 1.73 * 415 * PF

Answer / sunil bhatt
Formula is here
kva X pf = volt X current
for example
500kva x 0.8 pf = 44ov X Amp
I (amp) = 500000 x 0.8 / 440v
I (amp)= 400000 /440
I (amp)= 909 amp
So, Put your available voltage & system power factor and
calculate your maximum out put current.

Answer / kola raju
The output current rating depends upon the load pf only
for example your pf is 1.0 then output is p=v*i*pf =
500kva/(415*1.0)=696 amps
if your load pfi s 0.8 500kva/(415*.8)=555 amps only

WE ARE PLACE A NEW 75 KW MOTOR FOR JPF.IT IS CONNECTED IN M.C.C. WHEN WE ARE STARTING M.C.C.INCOMER IS TRIPPED.THEN WE ARE CONNECTED IN P.C.C WITH A MM30 RELAY PROTECTION THEN WE ARE STARTED MOTOR WILL RUN SMOOTHLY.
