Answer / sanjay singh artemis health i

Mr Ram
its depend on voltage & system is single or 3 phase
but i am giving example for 3 phase 415 V
P= 1.732xVxIxcosQ for 3 phase
so first we need change the KVA to KW
1kva = 1x.8(pf)
=.8kw or .8x1000 Watt
I am giving example .
considering,
V=415VOLTS
3-PHASE
P.F=08
P=1.732xVxIxCOSQ
I=.8x1000/1.732*415*08
I=1.39amps

ok

Answer / pari

In single phase circuit
1 KVA= 1000 VA
Amps= 1000/230=4.34

In three phase circuit
Amps=1000/(Root3*440)=1.31

Answer / sanjay

u must know the voltage rating for calculating ampere n
whether it is three phase or single phase...

Answer / subbu

i am giving example for 3 phase 415 V
P= 1.732xVxIxcosQ for 3 phase
so first we need change the KVA to KW
1kva = 1x.8(pf)
=.8kw or .8x1000 Watt
example:-
V=415VOLTS,3-PHASE,P.F=08
P=1.732xVxIxCOSQ
I=.8x1000/1.732*415*08
I=1.39amps

Answer / vijay kumar

1Kva=1.4Amp.

Answer / raju,

P=1.732*415*0.8/1000*I(Ex:- P=1600KW)kva =2000

=575.02/1000*I

I=1600000/575.024
I=2782.4

2000kva=2782.4A
1kva=?

1kva=2782.4/2000
=1.39A

Answer / ram

Mr kavi,
You are not specified voltage.
I am giving example .
considering,
V=440VOLTS
3-PHASE
P.F=08
KVA=1.732xVxIxCOSQ
I=1000/1.732*440*08
I=1.64amps

ok

Answer / umang

Depends on the voltage and whether the system is single
phase or 3 ph
