how to amps calculate from 1KVA?..

Answer / pillay

1 KVA means 1000 volts amps for single phase calculations

1 KVA means 1000 volts amps x 1.732 for three phase

so for 240v single phase is 1000/240=4.16 A

SO FOR 3 PH @ 415 V= 1000/415/1.732=1.39A

SO FOR 3 PH @ 440 V= 1000/440/1.732= 1.31A

SO for easy average easy calculations you can take 1.35 AMPS
for 1 KVA for 3 p;h calculations

how to amps calculate from 1KVA?..

Answer / janakiraman

kva is nothing but the voltage and current are directly
propotinal and there is no phase difference between them.

Is This Answer Correct ?    0 Yes 1 No

how to amps calculate from 1KVA?..

Answer / be1

KVA=S , so you should know that S=Rt.(R^2+Q^2)
S=P*pf ---- (pf means power factor)
S=U*I*pf but in 3 phases you have
S=Rt.3*U*I*pf

Is This Answer Correct ?    1 Yes 3 No
