if we convert kva into Ampers,which one formula use by us,pls tell me?..

Answer / jagadisha bmsit

kVA= True power*Cos(PI)
= V*I*Cos(PI)
I=kVA/VCos(pi)

Answer / thanigai1984

P=VI cos@ cos@ is power factor

P=KW KW=KVA*Power factor

KVA*pf=VI*pf
KVA=VI
I=KVA/V

Answer / rajpoot

If, we convirt KVA INTO AMP, following formula wil be
appliesd.

I= P/V*Cos(PI) ...........for single phase

OR I = KVA*800/[V*Cos(PI)]

I= P/1.732*V*Cos(PI) ...........for three phase

OR = KVA*800/[1.732*V*Cos(PI)]

Answer / khalidshaikh

AS FROM QUESTION REPLY AT SR NO 1 IS RIGHT.
BUT REPLY AT SR.NO 02 IS ALSO RIGHT, BECAUSE WHEN EVER
ENERGY CONSUMED ,THERE IS SOME LOAD POWER FACTOR, WHICH IF
IMPROVED THAN AMPERS OF THE SAME KVA REDUCED AND VICE VERSA.
