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)]
