Answer / kumar

as per my field knowledge by using formula
I= KVA X 1000/1.732 X 440 X 0.8

THERFORE ANSWER IS :1694A

Answer / mohamed ali

Dear there are use the Formula
I= KVA X 1000/1.732 X 440 X 0.8

100 % - 1669 Amps
80 % - 1335 Amps
So always put in Amps 80% mean 1335 Amps

Answer / mohamed ali.m

Dear there are use the Formula
I= KVA X 1000/1.732 X 415

For Example

1200KVA
1200x1000/1.732x415= 1669.4 ( Full load Amps
= 1335.5 ( 80% Load Amps)

Answer / a.bala

As per manufacture recommendation 80 % load can be
possible in continious operation mode . APPX 1300A
or
/ day hour basis u can load up to 100 % APPX 1700 A

Answer / soma

AS SAME

Answer / thran

1668 exactly amps rating!

Answer / deepak tyagi

KVAX1000= 440XIX1.732

I=1200,000/440X1.732
I=1574 AMP.
WE CAN DRAW THE MAX. CURRENT 1574 AMP.

Answer / vijay

hey guys i think it depends on the power factor
if it is 0.9 then 1200kva*0.9=1080 kw
if it is 0.8 then 1200kva*0.8=960 kw
now you can use your formula
p=sqrt3*V*I*Cosphi watts
I=P/sqrt3*V*Cosphi amps
I=(1080/sqrt3*440*0.9)*1000=1576 amps for 0.9 pf
I=(960/sqrt3*440*0.9)*1000=1401 amps for 0.8 pf

Answer / vijayakrishnan

KW= KVA X PF
please don't include the P.F
I = KVAX1000/1.732XV
I=1200X1000/1.732X415
I=1669.49
now we will be take only 80%
so we take 1335A only

Answer / nikhil shinde

assume, pf=0.8
then
1200*0.8=960 KVA

I=kw*10^3/1.732*v

=1335.55 @100%
=1068.44 @80%
