how do you solve for power factor when KW and PF are unknown?
KVA is 351.25
I = 422
Three phase 1.732
This maybe a stupid question, but how do I solve for KW or PF without knowing either one?

PF = Kw/ sqrt (Kw^2 + Kvar^2)
Kva = sqrt (Kw^2 + Kvar^2)
Pf = cos angle between voltage and current
In order to calculate PF you must know two of the following: Kvar ,Kw , Kva, angle between voltage and current.
