1 KW = how many kva ..

Answer / jay

KW+KVAR=KVA
you have to find kvar (Reactive power)

If you know the KVA and KW the formula is KVAR = Sqrt(KVA^2
- KW^2).

using the power factor and KW, find the phase angle (the
power factor is the cosine of the angle) which will allow
you to determine the tangent of the phase angle. Then the
following formula will work KVAR =KW * Tan theta

Using the same principle, find the sine of the phase angle,
then KVAR=KVA * sin Theta
