Answer / nick a.
square root of 3 (1.732) x E x I /1000 =kVA (3 ph )
E x I / 1000 = kVA
120 x 60 =720 /1000 = kva (single phase)

Answer / prithvi narayan sinha
kw/kva=cos(phi)
therefore kVA=kW/cos(phi)

Answer / aayush
For Single Phase-
P (KVA)= V (Volts) * I (Amps)/1000
For Three Phase-
P (KVA)= 1.732 * V (Volts) * I (Amps) * CosQ/
1000

Answer / joban
p=VxI/1000 in singl phase
p=root3xVxIxCosphi/1000

Answer / nani
some pepole are writing for power actually asking for how
to calculate KVA.
| Is This Answer Correct ? | 8 Yes | 1 No |
Answer / arun reddy
Take 3phase Current for Example.
R-24, Y-29, B-27.
24+29+27=80amps
80X230 (output volt)
18400/1000=18.4KVA.
